Default Please help me in this trigonometry problem?

Solve the following trigonometric equations (1-4).Give all positive values of the angle between 0* and 360* that will satisfy each.Give any approximate value to the nearest minute only.1.) cos 2x - sin^2 x/2 + 3/4 = 02.) cos 4x = sin 2x3.) 3 sin (theta) - 4 cos (theta) = 24.) tan (x+15*) = 3 tan xVerifythe identity:1.) tan (2 tan^-1 x) = 2 tan (tan^-1 x+tan^-1 x^3)
