Question

How to solve sine equations?

Answer 1

Do you have an example?

Answer 2

No, I'm just teaching myself about it. I'm wondering how to solve things like sine equations in triangles.

Answer 3

depends on the context

Answer 4

\[
r\sin(\theta)=x
\]

Answer 5

This is the first fundamental thing about sin you must understand.

Answer 6

Side of triangle / sin opposite angle= another side of triangle / sin opposite angle

Answer 7

You must also know how cos and tan works as well in this respect.

Answer 8

Yeah, like that. If one side was a square root, ex. square root of 23, how would you solve that? Lets say line AB was 4 and BC was 11, and AC was the sq root of 23?

Answer 9

Is it a right triangle?

Answer 10

Yes.

Answer 11

Those numbers do not make a right triangle if you do Pythagorean's theorem.

Answer 12

Haha I'm sorry. I'm just trying to figure out how to work sine equations. What would fit the right triangle?
