Remember that the Taylor series expansion of a function f(x) is equal to
f(a) + f'(a)(x-a) + [f''(a)(x-a)^2]/2! + ...
In the MacLaurin series expansion, a=0, so the first three terms are
f(0) + f'(0)x + [f''(0)x^2]/2!
f(0) = sin(2 x 0) = sin(0) = 0. This ...
In this solution, we find the first three nonzero terms of the MacLaurin series expansion for the given function.
