Question

if theta is a positive acute angle then find theta from equation 4sin^2 theta-3=0

Answer 1

Answer:

in a triangle let's suppose that one angle or angle A be 30° . then sin 30° = 1/2 and cos 30° =√3/2 . Sin 2 theta is the sine of the angle which is double the value of theta. This can be used when you know the value of sine and cosine of theta and not 2 theta.
