Learn how to solve problems step by step online. Find the integral int(e^(-x)cos(1/3)x)dx. The cosine of \frac{1}{3} equals . The integral of a function times a constant (0.944957) is equal to the constant times the integral of the function. We can solve the integral \int e^{-x}xdx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du.
