Following my comment above: the function f(x, a) = cos(ax) f (x, a) = cos (a x) is regular enough (continuously differentiable, at least) for Detailed step by step solution for integral of (cos(x))^4 Now, in order to integrate the given cosine function what we need to do is use the cosine identity as follows: cos2 x = 1+cos 2x 2 cos 2 x = 1 + cos 2 x 2. So, now we need to integrate ∫cos4x dx and applying the identity we get, Now, applying the identity again and integrating using the fact that integration of cosx is sinx and 1dx is x we get
Integral of (cos(x - Wolfram|Alpha
Solution. Step 1: Simplify the given function. Given function: cos 4 x. We can write the given function as, cos 4 x = cos 2 x cos 2 x (1) We know the double angle cosine formula Expand the result and apply the principles of this Key Idea again. We practice applying Key Idea 11 in the next examples. Example 1: Integrating powers of sine and cosine. Evaluate ∫sin5 xcos8 x dx ∫ sin 5 x cos 8 x d x. Solution. The power of the sine term is odd, so we rewrite sin5 x sin 5 x as \[\int \cos^{4}x \, dx\] +. > The formula of integral of sin contains integral sign, coefficient of integration and the function as sine. It is denoted by ∫ (sin 4 x)dx. In mathematical form, the integral of sin^4x is: ∫ sin 4 x d x = 3 x 8 – sin (2 x) 4 + sin (4 x) 32 + c. Where c is any constant involved, dx is the coefficient of integration and ∫ is the symbol
