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