$\frac{1-\cos\left(5\cdot 0\right)}{3\cdot 0^2}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(0)lim((1-cos(5x))/(3x^2)). Evaluate the limit \lim_{x\to0}\left(\frac{1-\cos\left(5x\right)}{3x^2}\right) by replacing all occurrences of x by 0. Multiply 5 times 0. Calculate the power 0^2. The cosine of 0 equals .
