can you right cot (x) in terms of sin and cos

I wrote cot(x)=cos(x)/sin(x)
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
And then i cancelled the cos(x)
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
And i was left with sin(x) = sqrt(3)/2
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
now can you write what answer you got
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
I then thought i can get infinite answers....
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
So i wrote pi/3 and 2pi/3
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
I think there are more solutions but i dont know how to writee them
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
..... ok can you tell me what is th sin invers of \[\sin^{1}( \frac{ \sqrt{3} }{ 2 })\]
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
It is pi/3 and 2pi/3 between 0 and 2pi
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
How you got 2pi/3
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
I did pi  pi/3 because sin is also positive in that quadrant
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
yes exactly.. so when we find inverse if get more values we take the lesser value usually.. for example 7pi/3 is also giving same answer but by using the concept above answer will b what?
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
is it pi/3?
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
But i need to state all the values for it
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
so i need to write, pi/3, 2pi/3, 7pi/3, 8pi/3, 13pi/3, 14pi/3 .......
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
How can i write this as a general solution
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
ok.. first take a look at pi/3 and 7pi/3 what can you find
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
any similarity?.. or relation... (clue can you relate with multiple of 2pi
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
Oo i think i found it
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
Is it pi/3 + 2kpi
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
and 2pi/3 + 2kpi
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
exactly.. ther you go... what is k...( no need to tll if you ar pretty sure)
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
And one more thing
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
Will i also need to evaluate cos(x)=0?
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
??? not clear... cab you make it more clear?is it another question?
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
if it is another qustion your answer is (2k+1)pi/2
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
No same one
 one year ago

baddinlol Group TitleBest ResponseYou've already chosen the best response.0
wouldn't 2cos(x) = sqrt(3)cot(x) if cos(x) = 0 also
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
am I clear?
 one year ago

Rosh007 Group TitleBest ResponseYou've already chosen the best response.0
ok...... asuming a fuction itself is zero may not lad you to corrct ansewr... also... here the cos (x) cancels each other (ofcourse before assuming it zero) hence assuming cos (x) = 0 is wrong..
