I wanna learn LaTex as quick as possible @Kitaw please help.

\begin{equation}
F_k(K,L,A)\geq0 \\
F_{kk}(K,L,A)\leq0 \\
\lambda F(K,L,A) = F(\lambda K,\lambda L,\lambda A)
\end{equation}

$$\lim_{k\to0} {F_k(K,L,A)} = \infty $$

$$ \lim_{k\to\infty}{F_k(K,L,A)} = 0 $$

$$U^'(C_t)>0 \ and \ U^{''}(C_t)<0
$$

\begin{equation}
\max \ U = \sum_{t=0}^{\infty} (\beta\delta)^{t}U(C_t)
\end{equation}
