# Math Help - find the value of tan sin and cos

1. ## find the value of tan sin and cos

thanks

mine is

1. 56/33
2. -24/25
3. 63/65

2. Which quadrants are $A$ and $B$ in?

3. All seem correct to me.

@Prove It: It says A and B are in Quadrant 2.

4. they are in quadrat 2 guyz

5. @educated,, did u try to solve them

thank you very much

6. Yes I did. They were correct.

A = 2.214297436...
B = 1.965587446...

tan(A + B) = 1.6969696969... = 56/33

sin(2A) = -0.96 = -24/25

cos(A - B) = 0.9692307692... = 63/65
