Question

If theta is 90 degree then sin to theta

Answer 1

sin2θ = 2(sinθ)(cosθ)

Since we know that θ=90, sinθ = sin90 = 1 and cosθ = cos90 = 0

By putting value...

2 x 1 x 0 = 0

Hope it helped u.. Pls mark as brainliest :)

Answer 2

Answer:

if theta is 90 degrees we can figure out

Sin Theta = Cos (90° - Theta)
