Assume that sin(x) equals its Maclaurin series for all x. Use the first two terms of the Maclaurin series for sin(7x^2) to approximate the integral:
The Attempt at a Solution
If I understand correctly, a Maclaurin series is just a Taylor series centered at 0. Therefore, my first two terms would be:
I feel like I'm getting off on the wrong foot right away.
