Question 62680: I have this problem and I need to solve it using Identies, but it also has restrictions such as theta is more than or equal to zero and theta is less than or equal to 360 the equation is this 4cos(squared, theta)-1=0
Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
cos( theta ) = +- 1/2
x = /3
x = 2/3
x = 4/3
x = 5/3
