I was taking 2nd semester calculus (spring of '78) and the prof called on students to go to the board and solve a problem from the homework set. I had done all the homework, and had to do the proof that a particular function was continuously differentiable. Having just finished a refresher on college algebra the semester previous, I whipped that proof right out. I was pleased with myself, for sure. You should be, too, for your proof! Rewarding, isn't it?
