Conquering trigonometric integrals in Calculus 2

4 Z (1 2cos(2x) + cos2(2x))dx = 1 4 Z dx 1 2 Z cos(2x) + 1 4 Z cos2(2x)dx and we have already learned above how to handle each of these integrals. We can use a similar approach, using formula (2.2) instead of (2.1) to handle Z cos4(x)dx: 6. Using trigonometric formulas to compute trigonometric integrals: Part III In this section we handle ... ................
