# Canceling Non-existent Limits

Calculus Level 1

True or false:

Because both the limits, $$\displaystyle \lim_{x\to\infty} \sin x$$ and $$\displaystyle \lim_{x\to\infty} \cos x$$ does not exist, then the difference of their limits must be equal to 0:

$\lim_{x\to \infty} ( \sin x - \cos x) = 0 \; .$
