comment Multiplying exponents by fractional exponents and whole numbers to the power of fractional exponents
Why are you dividing the exponent by 2?

comment What is the difference between the rowspace and the columnspace in linear algebra?
@weezybizzle Define what what you mean by solution space. Do you mean the space the row/column space lives in? In that case, column space is a subspace of $$\mathbb{R}^{m}$$ for some m x n matrix, and the row space is a subspace of $$\mathbb{R}^{n}$$

comment twice differentiable function (question from exam)
@rick, any indication that you've worked on this problem yourself would most likely generate a much greater response from the community. No one here wants to do your homework for you, but most people would be willing to teach you how to do it yourself. That being said, you may be so lost you have no idea of where to begin. That's ok too, just communicate that.

comment Tranforming 2D outline into 3D plane
What is your end goal? If you want the user's (2D) shape to be interpreted as a plane in 3-space, I think you're going to have to make some additional assumptions. As it stands, the sketch you provided could be a rectangle angled away from the camera, or a trapezoid parallel to the plane of the camera. More specifically I suppose, what role does the rectangle at at (0,0,0) play?

comment Can we consolidate the definition of “critical point” in one-variable calculus?
Whoops, that's an embarrassing mistake for my first answer here. What I get for typing quickly and trusting Lion to spell check I suppose. Thanks.
