Can you help me? Must be on paper.

3. Find the Taylor series centered at r = 2 of the following function. (3 points) f(x) = 3x3- 14x + 21x - 9 4. Use the series expansion of sin(x), cos(r) and er, to find the limits. (2 points each) r sin(x) - 12 (a) lim 140 cos(x) - 1 + +2/2 2x - 1 - 2x - 2x2 (b) lim
