Nevermind, I found the section in my book that discusses this, and I've figured it out. Seems like that usually happens right after I ask the question.

Homework Statement For the quadratic form x2-2xy+2yz+z2: a) Find a symmetric matrix that allows the quadratic form to be written as xTAx. b) Determine if the critical point at the origin is a minimum, maximum, or neither. c) Find the points for which the quadratic form achieves its...

Of course I figured it out after asking. First I figured out that the Fk = n*.200, or cos(38)*(9.8)*(4)*(.200) = 6.178. Next I figured out the force due to gravity, Fg = sin(38)*(9.8)*(4) = 24.134. Add the two together and divide by mass (4kg) to get acceleration of 7.578. Plug...

[SOLVED] Block released from spring slides up a ramp Homework Statement Homework Equations I'm thinking conservation of energy: K1+U1+WOther=K2+U2 But really I'm not quite sure where to start here. The Attempt at a Solution So far, I've calculated the velocity of the block after...
