Some of you may have heard Richard Feynman talk about a notation he invented for trigonometric functions to give them a more symbolic representation. He stopped using the notation in his teens and I can't find any published examples of it so I had to make assumptions as to what it would ...
- what must you do when you find your answer in terms of theta? What must we do to these functions to set them up for trig sub -what is the a^2 and u^2 values? **What if you have to use multiple/various substitutions -what do you do to the answer after you have done trig ...
