However, sin (A + A) is really sin 2A. So, sin 2A is sin A cos A + cos A sin A. They are both the same product, in opposite order, so this statement can be simplified to sin 2A = 2 sin A cos A. Similarly, cos 2A = cos A cos A - sin A sin A,

If we had to solve sin x = ½, for example, we would have x = 45° or x = 135°. ( Topic 4, Example 1 .) In the following example, we will see how this ambiguity could arise. In triangle ABC, angle A = 30°, side a = 1.5 cm, and side b = 2 cm.
