Do you know the trigonometric identities? Sin and cosine?

cosine =adjustment/hypotenuse right

Not so fast. So we know that \(a=50\) degrees. \(\cos a=\frac BC\). \(C\) we know is \(90\). So yes, to solve for B, you would use \(B=90\cos a\).

cost 50=confused
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
Yes. Multiply both sides by \(90\).
 one year ago

Claire4christBest ResponseYou've already chosen the best response.1
you multiply 50x90 right
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
No, you multiply 90 by cos 50.
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
\[90\cdot\cos50\neq90\cdot50\]

badreferencesBest ResponseYou've already chosen the best response.1
That sounds off.

badreferencesBest ResponseYou've already chosen the best response.1
Do you know how to do \(90\times\cos50\)?
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
No, \(\cos\) is an operation.

im getting 4,500 for some reason
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
Alright, do you know what an operation is? \(\sin x\) and \(\cos x\) are like machines into which you put a number \(x\) and retrieve a value. So do \(\cos50\) first.

if i do 50 cos=0.9649

badreferencesBest ResponseYou've already chosen the best response.1
\(50\cos\neq\cos50\).
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
It's not a multiplication.

Claire4christBest ResponseYou've already chosen the best response.1
i click on cos and than i put 50 so i got 50

I have no idea what you're talking about. You sound confused. Do you know what \(\sin x\) is?
 one year ago

Claire4christBest ResponseYou've already chosen the best response.1
yes on calculator
 one year ago

badreferencesBest ResponseYou've already chosen the best response.1
No, even more importantly, \(\sin x\) is an operation performed on \(x\). You're used to operations like \(+,,\times,\div\), but \(\sin x\) is an operation like that. You can't just move the \(\sin\) around.

@swissgirl @bahrom7893 I can't tell what the confusion here is. Help me!

@nincompoop You are a better teacher.

swissgirlBest ResponseYou've already chosen the best response.1
Ok well on your calculator you should have this button called sin, cos and tan correct?
 one year ago

swissgirlBest ResponseYou've already chosen the best response.1
allrrighhttyy so on your calculator type 90*Cos(50) then press enter
 one year ago

swissgirlBest ResponseYou've already chosen the best response.1
ohhhh u r on radians. You gotta set your calculator to degrees

oh that's the problem

i dont know why im getting 4,500
 one year ago

Claire4christBest ResponseYou've already chosen the best response.1
what i did is 90xcos50
 one year ago

Claire4christBest ResponseYou've already chosen the best response.1
you don't multiply when its cos(50) right
 one year ago

swissgirlBest ResponseYou've already chosen the best response.1
90*50=4500 But we are typing 90*Cos(50) remember to include the Cos

@lgbasallote YOU.

The second most powerful. Most powerful is undoubtedly CleverBot. :P

badreferencesBest ResponseYou've already chosen the best response.1
Unfortunately, CleverBot is not programmed to give you right answers. Just data mine a lot.
