If I have this problem: lim as h -> 0 And I have these answer choices: A. B. C. D. E. What does this really mean? like, I don't understand what f'(0) would imply, for instance.

What does this really mean? like, I don't understand what f'(0) would imply, for instance. If a function f(x) is defined on a point and in some neighborhood of this point , the definition of the derivative of f in this point is: , in case this limits exists and is finite. Can you see now what option to choose? Tonio
So ... Would it be choice a? Since if I put in pi/2, then that means that f(x) would equal 1 since sin(90)=1.
Yes, that is correct. (Although I would prefer " " to "sin(90)= 1"! You need to start thinking in radians, not degrees.)
Yeah, I would ahve thought that. Thanks.
