## [answered] Math 153 FINAL TH PORTION Name (Last, First): 75 pts SCORE

Calculus III (Community College Level) Final Review sheet. I wasn't able to grab the answer sheet in class, so I have no idea if the answers and methods I'm using are correct.

This sheet covers Power Series, Function Rep. of Power Series, Taylor/MacLaurin Series, Vector Functions (in regards to position, speed, and acceleration), and parametric equations of Planes/Lines.

Please complete the worksheet and show ALL WORK. Like, every single step as if you were teaching it to someone. Small algebra calculations can be done in head and not required to write down.
