Ah, of course! Me so dumb. Thanks a lot. :)

No, I know that's how it works, but I guess my question is, why isn't the derivative of 100 being taken as well? Why is it being left out? Sorry for the dumb questions. :/

But can't you do that only if the 100 is being multiplied in both x and y? I mean, the way it is, wouldn't it only be multiplying to either the X or the y, not twice to both of them?

Yeah, I felt it had something to do with the product rule, but why did they take out the 100 like that?

My next question is, in my book, they differentiate d/dx(100xy) and turn it into: 100[x{dy/dx) + y] How did they get to that?

Find y' = dy/dx for x3 + y3 = 4 Okay, now what's really confusing me is that for the y3 is that you need to use the chain rule for it. When you do, the answer is 3y2(dy/dx). How does that actually work? And if anyone can give me any good advice on any good guidelines on how to properly...

Homework Statement Okay, I have here the original equation that we start out with: f(x) = -2x + 4 Homework Equations I'm supposed to find the slope of that equation. Which is obvious, since it's -2. But I was supposed to show how it's consistent with the limit definition of...
