Verify an identity using the sum and difference identities for cosine. Use a double angle identity to get everything in terms of one angle, then use the zero product property to factor and solve. So it doesn't matter what the angle is R is just 4 so pick an angle 1 Examples of inverse trig function values, and finding compositions of inverse and regular trig functions. The process for this problem involves a difference identity for sine, and then a multiple angle. The multiple angle means that we ... Verifying identities involving the sum and difference identities for sine.
