    I need check about these :

    A) Solve the following, giving all positive values of the angle between 0° and 360° to the nearest minute only.

    i) cos2x-sin^2 (x/2)+3/4 = 0
    ii) cos4x =sin2x
    iii) sin^2 theta = cos^2 theta +3/2
    iv) sin(2x-10°)= 1/2
    v) sin2x-cosx = 0

    b) Write equivalent equations in the form of inverse functions for :

    a) x= y+cos(theta) b) cosy = x^2
