have you learned limits, limit based formula, derivative rules ?

i have no idea i just want to learn something ..please anyone can?

or anyone can give some easy example with step by step.

.... uhm... thats not going to be very easy, check out pauls online notes

differentiation takes quite a bit of prior knowledge

ah ok, so you understand what a derivative is by defenition, just not how to find it?

yup

ok so the limit based formula is: \[(f(x+\Delta x)-f(x)) \div \Delta x\]

this is just a rewritten formula for slope or dy/dx (y1-y2)/(x1-x2)

because x1-x2 is delta x or written as \[\Delta x\]

ok continue please

aka f(x+deltax)

hence we get that (y2-y1)/(x2-x1) = dy/dx = (f(x2)-f(x1)/(x2-x1) = (f(x+dx)-f(x))/dx

make sense?

ill post a picture of finding the derivative of x^3

wtf is that, stupid school computers

rofl i dont even know that kid
