LIMITS BY STANDARD EXPANSIONS. Write down the first two non zero terms in the expansions of sin3x and cos2x . Hence find the exact value of. 3 x cos2 x − sin3 x . lim 3 . x → 0 3 x . sin3 x ≈ 3 x − 9 x 3 , cos2 x ≈ 1 − 2 x 2 , − 1. 2 2. Use standard expansions of functions to find the value of the following limit.

13 Φεβ 2019 · 1. How do you read f(x)? Solution: \F" of \X." 2. How do you read lim f(x) = L? x!a. Solution: The limit of \F" as \X" approaches \A" is \L." 3. How do you read lim. x!a. f(x)? Solution: The limit of \F" as \X" approaches \A" from the left. 4. How do you read lim f(x)? x!a+. Solution: The limit of \F" as \X" approaches \A" from the right.
Limits are a very powerful tool in mathematics and are used throughout calculus and beyond. The key idea is that a limit is what I like to call a \behavior operator". A limit will tell you the behavior of a function nearby a point.
Kuta Software - Infinite Calculus. Evaluating Limits. Evaluate each limit. 1) lim 5. x→−1. 5. 3) lim ( x3 − x2 − 4) x→2. 0. 5) lim − x + 3. x→3. − 6. x − 4. 7) lim −. x→1. x2 − 6 x + 8. 1. 9) lim sin ( x) x→ π. 0.
