Pick a single problem type (e.g., finding velocity from position) and solve 5–10 practice problems. Then move to the next. Mastery comes from doing, not just reading.

Interpretation: We take two points on a curve, bring them infinitely close together, and measure the slope of the resulting tangent line. Pick a single problem type (e
Meaning: If you integrate a function and then differentiate the result, you get back the original function. | Integral ( \int f(x) , dx )
