,Feynman’s Favorite Trick, the integral.where α is the so-called . of the integral (. the dummy variable of integration which is, of course, x), then we wish to calculate the derivative of I with respect to α. We do that in just the way you’d expect, from the very definition of the derivative:

,‘Easy’ Integrals,You should always be alert, when confronted by a definite integral, for the happy possibility that although the integral might look ‘interesting’ (that is, hard!) just . it will still yield to a direct, frontal attack. The first six integrals in this chapter are in that category. If a and b are positive constants, calculate:. and . and . and
