The formula of the cos (x^2) integral contains the integral sign, coefficient of integration, and the function as sine. It is denoted by ∫ (cos x 2)dx. In mathematical form, the integral of cos x2 is: ∫ cos x 2 d x = x − x 5 5 × 2! + x 9 9 × 4! + x 13 13 × 6! + + C. Where c is any constant involved, dx is the coefficient of 5 Answers. cos4(x) = (1 + cos(2x) 2)2 = 1 + cos2(2x) + 2cos(2x) 4 = 1 + 1 + cos(4x) 2 + 2cos(2x) 4 which gives us cos4(x) = 3 + 4cos(2x) + cos(4x) 8 Now you should be able to integrate this off.

The integral of (cos(x))^4 is cos^3(x)sin(x)+3/8 (x-1/4 sin(4x))+C Trigonometry. Solve for x cos (x/4)=0. cos (x 4) = 0 cos (x 4) = 0. Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. x 4 = arccos(0) x 4 = arccos (0) Simplify the right side. Tap for more steps x 4 = π 2 x 4 = π 2. Multiply both sides of the equation by 4 4
