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