Let $f:\mathbb{R}\rightarrow\mathbb{R}$ be twice differentiable function. Suppose $a<c<b$ such that $f'(c)=0$ and $f''(c)>0$. Then $c$ is a local minimum of $f$.

In my cryptography course I found the following problem: Find $|E(\mathbb{F}_{7^{100}})|$ where $E$ is given by $y^2=x^3+1$.

Recall that a poset $P$ is said to be continuous if, for every $p \in P$, the set $\{q \in P \mid q \ll p \}$ is directed with supremum $p$.

I don't need a completely formal explanation, just some intuition. My professor stated identifying antipodal points on $S^1$, yields the projective plane $P^2$.
