$\frac{\left(1-\cos\left(0\right)\right)^2}{0}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of ((1-cos(x))^2)/x as x approaches 0. Evaluate the limit \lim_{x\to0}\left(\frac{\left(1-\cos\left(x\right)\right)^2}{x}\right) by replacing all occurrences of x by 0. The cosine of 0 equals . Subtract the values 1 and -1. Calculate the power 0^2.
