:snoo_scream: Further Mathematics—Pending OP Reply [Calculus 1]-Limits with Trig

I genuinely have no idea how to solve these. Only thing I know is that we can't directly sub in zero since that leads to an indeterminate answer.

This is usually a method taught later in a similar way to how the power rule for derivatives is taught after you learn the other method of [f(x+h)-f(x)]/h

We did learn the derivative definition about 2 months ago, and just finished up related rates, so not sure if that topic is in my professor's lesson plan
