From: alfredo
Subject: Partial and directional derivative, gradient
I don't understand the definitions of partial and directional
derivatives and gradients. Could you explain the meaning and relations
between them?
Thank you.

The Exponential Curve
I'm not planning our Algebra 1 classes this year, so I have not been producing much for it. But I did put together a scaffolded introduction to inequalities. The objectives are for students to:

Prove that 2 is a primitive root modulo p.
Suppose q is a prime and p=4q+1 is a prime. Prove that 2 is a primitive root modulo p.
First observe that $2^{\frac{p-1}{2}}\equiv\pm 1 \mod{p}$. In this case, $2$ is a primitive root if and only if $2^{\frac{p-1}{2}}\equiv -1 \mod{p}$.
