Integration of Trigonometric Functions

1 2 (1−cos2x)dx. Note that the trigonometric identity is used to convert a power of sinx into a function involving cos2x which can be integrated directly using Key Point 8. (b) Now evaluate the integral: Your solution Answer 1 2 x− 1 2 sin2 +c = 1 2 x− 1 4 sin2x+ Kwhere = c/2. Use the trigonometric identity sin2x ≡ 2sinxcosx to find Z ... ................
