Description
sintheta cos(90^(@)-theta)+costhetasin(90-theta)=sin theta *sintheta+costheta*costheta= sin^(2)theta+cos^(2)theta=1.
If sin theta + cos theta = root 2 sin(90-theta),then find the value of cos theta
What is cos90-theta? - Quora
evaluate cot[90-theta].sin[90-theta] / sin theta+cot 40/tan 50 - [cos square 20 +cos square 70]
How is sin (90°+θ) =cosθ? - Quora
prove that cot(90-theta) • sin(90-theta)/cos 90-theta) = 1
Prove that : (sinthetacos(90^0-theta)costheta)/(sin(90^0-theta))+(cost
