## Step-by-step explanation

Problem to solve:

$\lim_{x\to0}\left(\frac{1-\cos\left(x\right)}{x^2}\right)$

Learn how to solve limits problems step by step online.

$\lim_{x\to0}\left(\frac{\frac{d}{dx}\left(1-\cos\left(x\right)\right)}{\frac{d}{dx}\left(x^2\right)}\right)$

Learn how to solve limits problems step by step online. Evaluate the limit of (1-cos(x))/(x^2) as x approaches 0. If we try to evaluate the limit directly, it results in indeterminate form. Then we need to apply L'Hôpital's rule. The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}. The derivative of a sum of two functions is the sum of the derivatives of each function. The derivative of the constant function (1) is equal to zero.
