Find sin x and csc y
First of all how do use csc on a calculator (if possible)
of all how in the world do I set up the equations to solve?
I know that sin is opposite over hypotenuse and csc is hypotenuse over opposite

Best ResponseYou've already chosen the best response.2first ) apply the Pythagorean theorem to find 3rd side of right triangle \[\huge\rm a^2+b^2=c^2\]

Best ResponseYou've already chosen the best response.1okay so 25+49=74

cutiecomittee123

Best ResponseYou've already chosen the best response.1and the sqrt of 74 is the hypotenuse

Nnesha

Best ResponseYou've already chosen the best response.2\(\color{blue}{\text{Originally Posted by}}\) @cutiecomittee123 makes sense. so then to solve for sinx sinx=5/a \(\color{blue}{\text{End of Quote}}\) now substitute a for sqrt{74}

cutiecomittee123

Best ResponseYou've already chosen the best response.1do i keep it sin(x)=5/sqrt74 or do i simplify

Nnesha

Best ResponseYou've already chosen the best response.2yes simplify solve for x

Best ResponseYou've already chosen the best response.1i get a crazy weird number when i try to calculate that

Nnesha

Best ResponseYou've already chosen the best response.2what did you get ? first of all your calculator mode should be on degree 2nd you should take invs sin

cutiecomittee123

Best ResponseYou've already chosen the best response.1i get sinx=.0011792563

Best ResponseYou've already chosen the best response.2when we have to find an angle then we should use `invs sin` \[x = \sin^{1} \frac{ 5 }{ 8.6 }\]

Nnesha

Best ResponseYou've already chosen the best response.2or in other words `arcsin` http://prntscr.com/8eiznl

cutiecomittee123

Best ResponseYou've already chosen the best response.1okay so you just keep it that way, no more simplifying?

Nnesha

Best ResponseYou've already chosen the best response.2no use calculator to find x \[x = \sin^{1} \frac{ 5 }{ 8.6 }\]

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1alright so x=8.6

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2hmm not x isn't 8.6 the hypotenuse = 8.6

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2type this into the calculator \[ \sin^{1} \frac{ 5 }{ 8.6 }\]

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1it gave me 8.6

cutiecomittee123

Best ResponseYou've already chosen the best response.1wait no it gives me .0011792563

Nnesha

Best ResponseYou've already chosen the best response.2hmm not sure how u got that what did you type into the calculator ?

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1i typed x^1 before then sin(5/8.6)

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2it's sin^{1} not x^{1} arcsin =sin^{1}

cutiecomittee123

Best ResponseYou've already chosen the best response.1okay so 98.55

cutiecomittee123

Best ResponseYou've already chosen the best response.1that is what i get when i put the inverse second after the other part of the equation

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1x^1 is inverse

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2for that calculator press `2ndsin` then type (5/8.6)

cutiecomittee123

Best ResponseYou've already chosen the best response.1Ahh I see, way more acurate answer. x=35.55

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1okay and then we have to find the csc of y, an you help

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2i'll use the fact that all triangles add up to 180 degree so it's right triangle so one angle 90 other angle we just found 35.5 i don't knw why sin (x)= 8.6/7 gives me error on calculator

cutiecomittee123

Best ResponseYou've already chosen the best response.1alright, i dont know if you still want to help but there are two more and i think i have the hang of it, but it is always nice to have a little help:) find tan c and cot y and find cos x and sec y

Nnesha

Best ResponseYou've already chosen the best response.2geez i don't know why it csc y giving me an error anyways \[\huge\rm csc( x )=\frac{ 8.6 }{ 7 }\] then find inverse csc

cutiecomittee123

Best ResponseYou've already chosen the best response.1there is no csc button

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2i know but csc = 1/sin so it should be i /sin^{1}(7/8.6)

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1yes same triangle Okay let me try that

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1so plug in 1/sin(1) (7/8.6) ????

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2welll i plugged in sin^{1} (7/8.6) i got 54.48

Nnesha

Best ResponseYou've already chosen the best response.2still don't understand anyways move to the next one

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1waiiiiittt, are we still working on the first problem to find csc(y)? because i got the same answer y=54.5 because i just used your advice that there are 180 degrees in a triangle and we already have 90+35.5 and then i subtracted them from 180 and got 54.5 as well. I think that is the right answer

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2yes that's the right answer but i was trying to find how to find csc y without using the fact 180 degree :D

Best ResponseYou've already chosen the best response.2\(\color{blue}{\text{Originally Posted by}}\) @cutiecomittee123 alright, i dont know if you still want to help but there are two more and i think i have the hang of it, but it is always nice to have a little help:) find `tan c` and cot y and find cos x and sec y \(\color{blue}{\text{End of Quote}}\) do you mean `tan x` ???

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2alright try it first remember cot is reciprocal of tan

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1well tan(x)=5/7

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1Okay so I would just multiply by 7 on each side and that makes it 7tan(x)=35

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2well you don't have to multiply by 7 just take the invs tan and then calculator

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1okay so i did 2nd, tan(5/7) and i got 35.54

cutiecomittee123

Best ResponseYou've already chosen the best response.1i did it? is that it lol

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1okay so now to find cot y

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1wouldnt it just be cot y = 7/5

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1oh is it just tan(5/7)

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1well it is inverse tan so i figured you use tan when calculating

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2well you did the opposite tan = opposite over adjacent and cot = adjacent over opposite

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1so you keep it the way it is but just dont take the iverse? sine we took the inverse to find tan x

cutiecomittee123

Best ResponseYou've already chosen the best response.1inverse since *

Nnesha

Best ResponseYou've already chosen the best response.2guess what i'm so hungry right now i need 2nd opinion on this one i feel like we don't need angle we just write in the form tan x = 7/5 that's it

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2is it just find sin x or solve for x ?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2or like what is x and y ?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2\(\color{blue}{\text{Originally Posted by}}\) @cutiecomittee123 wouldnt it just be cot y = 7/5 \(\color{blue}{\text{End of Quote}}\) cot y = 5/7 ( adjacent over opposite) so it would be arctan(7/5)

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.2ye then cos = adjacent over hyp so same concept with sec just like cot i think ur afk

cutiecomittee123
 one year ago
Best ResponseYou've already chosen the best response.1okay i see. Thanks for your help!!!
