sin r 1 cos a , we should begin by cross-multiplying get rid of the fraction notation. To verify the identity 1+ cos z sin z If tan (2a) = 1, then a + na for any integer n. The first step in solving the equation cos = 1 is to apply the formula for the cosine of the difference of two angles. Cos a sin z In order to simplify 1- sin a a common denominator should first be found. Cos z V2 with b > 1 will always have less solutions than sin z because of the horizontal stretch by a factor of b. sin %3D cos a = 2 will have an extraneous solution. The equation tan a has no solution. The equation sin a = 1 has no solution.
