Compute: {{MATH_261}} {{CMD_262}} Before guessing the solution, let's express the function in the form convenient for integration. Due to Sum Rule, it is more convenient to have a sum of functions, instead of a single, complicated term. {{ENV_263}} Now, we can apply the Sum Rule. {{MATH_264}} Now we can finish the problem. {{MATH_265}} {{CMD_266}} {{CMD_267}}
