To find the Maclaurin series for (f(x) = \cos(5x^2)), we first need to find the derivatives of (f(x)) at (x = 0) to determine the coefficients of the series. Then, we express the function as an infinite series using those coefficients. The Maclaurin series for (f(x) = \cos(5x^2)) is:

[ \cos(5x^2) = \sum_{n=0}^{\infty} \frac{f^{(n)}(0)}{n!}x^n ]

To find the derivatives of (f(x)), we use the chain rule. The (n)th derivative of (\cos(5x^2)) is a combination of (\sin(5x^2)) and (\cos(5x^2)) terms. After evaluating these derivatives at (x = 0), we obtain the coefficients for the Maclaurin series.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
