Question

1) sin65 + sin43 – sin29 - sin7=? Angles are in degrees. ​2) sin(pi cot theta)= cos(pi tan theta) then cot2theta=? 3)cosxcosysin(x-y) + cosycoszsin(y-z) + coszcosxsin(z-x) + sin(x-y)sin(y-z)sin(z-x)=?

Ravi · Answer

2 Solve for tan(theta) and find the value of tan2(theta). Reciprocate to get to the value of cot2(theta) Requested to post only one question per post.
