In particular, if g(x) x3, this gives us cosx3.3x2dx sinx3 C, a result that is easily verified directly since theu to obtain (5.21), and then we think of u as representing a new function of x, say u g(x). Then we replace the symbol du by the combination g( x) dx We also know that the derivative of sin (x) cos (x) and that of cos (x) - sin (x). These facts helps us a lot in integration by trigonometric substitution. Powers of Sin and Cos. Example: Evaluate int sin5x dx we write.We pull out a cos x and convert the cos2 x to 1 - sin2 x: int sin2x (1 - sin2 x) cosx dx Let u cosx, du -sinx dx. Hint: let Iint :sinleft(xright)cos2left(xright)dx.Therefore: 3I-cos3left(xright) C which led to Ifrac-cos 3left(xright)3 C. I think you can continue from here. This is another easiest method, if you dont like substitution. Int[sin(x)]dx -cos(x) c Bring the -2 outside the integral sign to give -2 Int[sin3(x)]dx.
