Compute: {{MATH_278}} {{CMD_279}} Since the integrand here is an exponential, we'll start with a guess of an exponential. {{MATH_280}} Differentiate our guess to check it: {{MATH_281}} It appears that we are off by a constant factor. We will divide by {{MATH_282}} to get rid of the coefficient on the right-side. {{MATH_283}} We need a coefficient of {{MATH_284}} for the exponential, so we multiply by {{MATH_285}}. {{MATH_286}} That gives our result. {{MATH_287}} {{CMD_288}}
