Improve your u-sub

U-substitution ( change of variable) is the most used integration strategy in calculus. We start small, but with time, we see that it becomes more efficiant if we replace a bigger portion of the integrand the very first time. nless interrupted by another integration strategy, any time you used u-sub more than once, it's a sign you did not take enough the first time.
