Question:

True or false: you should never guess on a multiple choice answer if you have no idea what the answer is since you'll lose points.

Clara N.

Since the test was redesigned, the guessing penalty is a thing of the past. And even when the penalty was in place, it was designed to render uneducated guessing not-advantageous, but it was never actively disadvantageous.

Question:

How could the sentence, "It was unexpected and surprising for Richard when he found out what happened in Joseph and Ada's past history with each other." be rewritten for conciseness and clarity?

Clara N.

"Richard was surprised to discover Joseph and Ada's history together."

Calculus

Question:

If all trajectories in a vector field F[x,y] = {m[x,y], n[x,y]} point towards (3, 4), and F[x,y] is a gradient field for a function f[x,y], what can we say about f{3, 4}?

Clara N.

Gradient vectors point in the direction of greatest initial increase in a function; a trajectory following a=gradient vectors ends up at approaching a maximum or saddle point unless it begins at such a point. if all trajectories lead to {3, 4}, there must be a maximum there. f[3, 4] is greater than f[x,y] for all other (x, y)
