Expand cos x in powers of x
Web2.2 Integral with Trigonometric Powers. Example 2.14. Odd Power of Sine. Evaluate ∫ sin5xdx. ∫ sin 5 x d x. Solution. Observe that by taking the substitution u= cosx u = cos x in the last example, we ended up with an even power of sine from which we can use the formula sin2x+cos2x = 1 sin 2 x + cos 2 x = 1 to replace any remaining sines. WebApr 26, 2024 · Recall that. cos(2x) = 2cos2x −1. Let x = cos2x and y = cos(2x). Then. y = 2x − 1. y + 1 2 = x. cos(2x) + 1 2 = cos2x. We can now use the fact that. cosx = 1 − x2 2! + x4 4! + ... = ∞ ∑ n=0( − 1)n x2n (2n)!

WebMar 26, 2016 · If you want to find the approximate value of cos x, you start with a formula that expresses the value of sin x for all values of x as an infinite series. Differentiating both sides of this formula leads to a similar formula for cos x: Now evaluate these derivatives: Finally, simplify the result a bit: As you can see, the result is a power series.
