Compute: {{MATH_268}} {{CMD_269}} Start with a guess of {{MATH_270}} Here, we used the {{MATH_271}} symbol to indicate that this is a guess, based on the integrand. Take the derivative of your guess to see if it is correct: {{MATH_272}} We're off by a factor of {{MATH_273}}, so multiply your guess by this constant. {{MATH_274}} That gives our answer. {{MATH_275}} {{CMD_276}} {{CMD_277}}
