WebbIn this unit, you'll explore the power and beauty of trigonometric equations and identities, which allow you to express and relate different aspects of triangles, circles, and waves. … WebbCould somebody please show why the following is a trigonometric identity? $$\dfrac{\sin^3 a - \cos^3a}{\sin a - \cos a} = 1 + \sin a \cos a$$ This problem appears on page $48$ of Gelfand's and Saul's "Trigonometry". (It's not homework.) It is probably the fact that we are dealing with trig ratios cubed that is throwing me off.
