InaneKorruption: Well that just made everything easier.
Yup, remember though that in general the derivative is actually the limit as h approaches 0.

so f'(x) = lim (h→0) (f(x+h)-f(x)) / h

Now in this example (a cubic function) it's quite easy, but in general it need not always be the case.

I got the point (-2,4). Is that the right answer?
It's this type of math that never makes sense to me, because i don't see how it can be applicable or even used, and it's more for solving specific problems that don't really have any grounding except in it's own math.

Math in programming is different, since you can see in order what needs to be done, and everything is defined for you, and if it isn't, there's logic to separate it out for individual steps. Easy most of the time.

Well that's good for me. I've applied for Computer Science in University (Grade 12 right now) and knowing that the math will be easier there definitely is a good sign.

Most of the math is probably making loops, or simple arithmetic. But I guess it depends on the application in question; If you're doing a 3D modeling program, you'll be dealing a bit with trigonometry, but doubtful to be anywhere as confusing as this example was.

Yes. Did you get the same answer using your calculator?
