Trigonometric identities sin 2 x + cos 2 x = 1 sin 2 x = 1 2 (1 - cos 2 x ) cos 2 x = 1 2 (1 + cos 2 x ) sin x cos x = 1 2 sin 2 x sin a cos b = 1 2 [sin( a - b ) + sin( a + b )] sin a sin b = 1 2 [cos( a - b ) - cos( a + b )] cos a cos b = 1 2 [cos( a - b ) + cos( a + b )]
Strategy for evaluating sin m x cos n x dx 1. If n = 2 k + 1 then sin m x cos 2 k +1 x dx = sin m x (cos 2 x ) k cos x dx = sin m x (1 - sin 2 x ) k cos x dx Then substitute

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
