What equation? Where? In general if you have an equation with lots of x and y type terms, you want to rearrange so you have y on the left and only terms with x in them on the right.

That is a fine substitution to make u = x + 1 dx = du x^2 = u^2 - 2u+1 so we have integral (u^2-2u+1)(u^.5) du that is integral of u^2.5 du - integral of 2u^1.5 du + integral of u^.5 du in general integral of u^n du = [u^(n+1)]/(n+1)

In the first case, maximum M2, both the component of weight down the plane and friction are in the down plane direction. They add, no minus sign. If the thing is to move the other way, down the ramp, the friction is opposite in direction, up the ramp. So...

That is the derivative. d/dt (t^3/3) = t^2 Since you asked for the derivative, I derived the derivative.

In general Look at the tangent to f(x) at x now look at the function a little bit further, at x + some little h if the curve is smooth, the tangent goes close to the point [(x+h), f(x+h) ] as the f(x) goes up or down between x and x+h now as h gets tiny,...

Look in the index of your calculus book for derivative, definition of derivative. They may explain it better or search on google for "definition of derivative" calculus

When I did that search, one of the first results was a " Wikipedia" article that does what I did with very nice graphs and stuff so it may be easier to understand than my trying to type it freehand.

That is completely correct Michael, but Britt asked where it came from. That is why I started with the definition.
