Question 2 2.1. If sin35=t, express the following in terms of t 2.1.1. sin325 2.1.2. cos35 2.1.3. tan215 (Hint: use a diagram) (2) (3) (2)​

Answer 1

Explanation:

sin 325=sin (360-35)=-sin 35=-t

cos 325=cos (360-35)=cos 35=√(1-sin²35)=√(1-t²)

tan 215=tan (180+35)=tan 35

`=(sin~35)/(cos~35) \\=(-t)/(√(1-t^2) )`
