$\frac{\cos\left(3\pi \right)+\cos\left(4\pi \right)}{\pi -\pi }$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(pi)lim((cos(3x)+cos(4x))/(x-pi)). Evaluate the limit \lim_{x\to\pi }\left(\frac{\cos\left(3x\right)+\cos\left(4x\right)}{x-\pi }\right) by replacing all occurrences of x by \pi . Subtract the values \pi and -\pi . Multiply 3 times \pi . Multiply 4 times \pi .
