Part 2 of which question?

Oh, that's more what I meant.

Alright, so then a derivative of a function at a point where x = a is the slope of the tangent to this function at the point (a, f(a)), is that right? I just thought I'd change the wording a bit so that it was a bit mroe clear for me.

I'm having trouble trying to figure out some of the questions from my homework, here are the problems: 1. A 68.5 kg skier rides a 2.56 m ski lift from the base of a mountina to the top. The lift is at an angle of 13.9 degrees to the horizontal. Determine the skier's gravitational potential...

I guess the best way to describe a limit would be the number that a function approaches as the variable approaches the number specified in the limit. That was a kind of awkward and rough explanation, I'm not really sure about how to explain it very well.

What do you mean? Are you referring to the fact that I didn't have all of f(a + h) - f(a) in the numerator? If so, then it's because I don't know how to post it the proper way. It's not often that I have to use LaTex coding.

As the moving point on the line approaches the point of tangency, the slope of the secant gets closer to the slope of the tangent. Here's what it said about the difference quotient: {f(a + h) - f(a)}/h This quotient is fundamental to calculus and is referred to as the difference...

That's what my textbook called it.

It's the limit that's used to find the slope of a tanget.

All I could find was this: "This limit(the difference quotient I believe it is referring to) is called the derivative of f(x) at x = a."

Centripetal force isn't really a force, it's more the sum of all forces acting on an object directed towards the centre of the circular path. From the looks of it, I'd say that the centripetal force in this case is supplied by the tension force. If the plane it was rotating in was vertical, then...

I don't know exactly, I know it sounds bad, but I didn't really understand the way the book explained it.

I missed the lessons at school for derivatives, and I'm not really understanding things from my textbook very well, so I'm hoping someone here can help me a bit with these problems. 1. In each case, find the derivative dy/dx a) y = 6 - 7x b) y = {x + 1}/{x - 1} c) y = 3x^2 The book...

First off, I obtained results that were way off. We were to study the effects of force, mass, and radius on the frequency of a spinning object. We were supposed to obtain slopes of 1/2 for the graph of each relationship, my radius graph was pretty good(0.56), my force graph wasn't very...

Identical squares are cut out from each corner of a rectangular sheet of tin 8cm x 6cm. The sides are bent upward to form an open box. If the volume of the box is 16cm^3, what is the length of each side of the squares cut out from the original sheet? I came up with the following equations to...
