my favorite calculus 2 trigonometry integral (two results off by a constant)

We will integrate tan(x)*sec^2(x) and we will see that we get two different results if we use different u-substitutions. This is my favorite calculus 2 trigonometry integral illustrating the results are off by a constant. For more calculus tutorials, subscribe to ‪@bprpcalculusbasics‬
