      7.2 Trigonometric Integrals The three identities sin 2x +cos x = 1, cos x = 1 2 (cos2x +1) and sin2x = 1 2 (1 cos2x) can be used to integrate expressions involving powers of Sine and Cosine. The basic idea is to use an identity to put your integral in a form where one of the substituions u = sin x or u = cos x may be applied. Examples 1.To ...

      r2 + 4r + 4 = 0 factors as (r + 2)2 = 0 so the solution is r = −2, repeated. Thus the general solution to the differential equation is y = C 1e−2x+C 2xe−2x. Using y(0) = 0 we get immediately that C 1 = 0, so the solution simplifies to y = C 2xe−2x. Then y0 = C 2e−2x − 2C 2xe−2x, and y0(0) = 7 gives C 2 = 7. So the solution is y ...
