Exercise 7.2.2. Evaluate ∫cos3xsin2xdx. Hint. Answer. In the next example, we see the strategy that must be applied when there are only even powers of sinx and cosx. For integrals of this type, the identities. sin2x = 1 2 − 1 2cos(2x) = 1 − cos(2x) 2. and. cos2x = 1 2 + 1 2cos(2x) = 1 + cos(2x) 2. Integration by parts is a technique used in calculus to evaluate the integral of a product of two functions. The formula for integration by parts is. ∫udv=uv−∫vdu. Here, u and dv are differentiable functions of x, and du and v are their respective differentials. Calculus is an advanced math topic, but it makes deriving two of the three equations of motion much simpler. By definition, acceleration is the first derivative of velocity with respect to time. Take the operation in that definition and reverse it. Instead of differentiating velocity to find acceleration, integrate acceleration to find velocity. I'm afraid that this is one integral where there is no nice form for the antiderivative. There are many ways to estimate the antiderivative. The simplest is to use the power series representation of $\sin(x)$.Learn Calculus 1 in this full college course.This course was created by Dr. Linda Green, a lecturer at the University of North Carolina at Chapel Hill.
