Calculus Thinking
A problem-solving state of mind that we assume when a problem looks frightening at first blush: We try to rephrase all or part of the problem in ways that are easier to recognize, that are more tractable, easier to solve. This could - and usually does - involve terrifying algebra (or trig, or ...), but! It will be worth it. The intuition and elegance that we show off in this process is the essence of Calculus Thinking.
