The derivative of f(x) is

lim h-->0 [f(x+h)-f(x)]/h.

So let f(x) = -5x. The derivative is

lim h-->0 [-5(x+h)- -5(x)]/h

= lim h-->0 [-5x - 5h + 5x]/h

= lim h-->0 -5h/h

Since the limit h-->0 of h/h is 1, the derivative is

-5

What does the derivative at a point mean?

The derivative at any point in a curve is equal to the slope of the line tangent to the curve at that point. Doing it in terms of the actual expression of the curve, find the derivative of the curve, then plug the x-value of the point into the derivative to find the derivative at that point.

How do you find second derivative of a function?

All it means to take the second derivative is to take the derivative of a function twice. For example, say you start with the function y=x2+2x The first derivative would be 2x+2 But when you take the derivative the first derivative you get the second derivative which would be 2

What is the third derivative of lnx?

Oh, dude, the third derivative of ln(x) is -2/(x^3). But like, who really needs to know that, right? I mean, unless you're planning on impressing your calculus teacher or something. Just remember, math is like a puzzle, except no one actually wants to put it together.


How do you find the derivative?

This is really too vague. There are tables for derivatives of common functions. There are rules for taking derivatives of polynomials. The derivative of f(x) is found by taking the limit of (f(x + ?x) - f(x))/?x, as ?x approaches zero.


How do you find the second derivative?
