Problem:
Important information about solving trigonometric equation
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
