Learn how to solve problems step by step online. Integrate the function -9xcsc(x)^2 from pi/4 to pi/2. The integral of a constant times a function is equal to the constant multiplied by the integral of the function. We can solve the integral \int x\csc\left(x\right)^2dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify or choose u and calculate it's derivative, du. Now, identify dv and calculate v.
