MCV4U Assignment Unit 4 I don’t remember what marks I got for this. There were mistakes here. Check the math to make sure it's right. Your welcome for saving you time. PS CourseHero sucks. 1. a) Given: ? 0 lim ??? ?;? = ??? ? Find: ? 0 lim ??? ?; Solve: Whether approaches from left or right (negative or positive sides), ? = ??? ? the curve approaches value cos x=1. Therefore, there is a limit of the function and it equals to 1 at x=0. b) Given: Find: ? lim ?𝑖? ? Solve: As it is impossible to determine the function at the infinity since the graph of the function is an oscillating curve, therefore, does not exist. ? lim ?𝑖? ? 2. Find the Derivative a) Solve: ? = ?𝑖? ? 5 ?' = 5? 4 · ??? ? 5 ; b) Solve: ? = ?𝑖? 5 ?
