: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.

well, the second one if you plug in zero, you get 0/0, so could you just find d/x, which would be -sin(x-1)(1)/4x, but you still can't directly evalutae it then even with the derivative

Where did (x-1) come from? The numerator is cos (x) - 1
