# limit definition of a derivative

1. (4) Use the limit definition of a derivative to show that 2. (8) Use the limit definition of a definite integral to find . . 3. (4) Find the extreme values of . Then, find the equation of the line tangent to y at its point of inflection. Label your answers clearly. Answers must be exact (no decimals). 4. (4) Find these limits. 5. (4) 6. (4) Last year in a baseball game, Christian Vázquez hit a line drive and started running towards 1st base at a constant 7.2 m/s. Xander Bogaerts was on second base. He started with a 2m lead off and ran with a constant speed of 8 m/s towards third base. How quickly is the distance between the two runners changing when Bogaerts reached third? All of the bases are corners of a square with 27.4 m sides. 7. (7) Calculate using the Fundamental Theorem of Calculus. 8. (8) Approximate using 5 middle rectangles. (Be sure to show all calculations!) 9. (10) The Chili Peppers are coming to ACL on October 14th!!
