What the problems look like

A few statements from this skill. Answers, hints and worked solutions live in the practice session.

  1. Warm-up

    Let F(x)=∫−2x(5t2+3) dtF(x) = \displaystyle\int_{-2}^{x} \left(5t^{2} + 3\right)\,dt. Use the Fundamental Theorem of Calculus (Part 1) to find F′(−2)F'(-2).

  2. Warm-up

    Let F(x)=∫0x(5t2+2) dtF(x) = \displaystyle\int_{0}^{x} \left(5t^{2} + 2\right)\,dt. Use the Fundamental Theorem of Calculus (Part 1) to find F′(−3)F'(-3).

  3. Warm-up

    Let F(x)=∫−5x(4t2−1) dtF(x) = \displaystyle\int_{-5}^{x} \left(4t^{2} - 1\right)\,dt. Use the Fundamental Theorem of Calculus (Part 1) to find F′(4)F'(4).
