3. The following is half of an identity:sec² x csc x/sec² x + csc² x =?Graph the left side on the coordinate axes with the window: [-27, 2?] by [-2,2]Label a few ticks marks on the axes.Use the graph to make a conjecture as to what the left side of the identity should be.Prove your conjecture. (Hint: first write the denominator in terms of sine and cosine)
