Equações Matemáticas

O Teorema de Pitágoras é dado pela fórmula: $a^2 + b^2 = c^2$
A fórmula de Baskara é a seguinte: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$
A soma dos primeiros $n$ termos de uma PA é dada por: $S_n = \frac{n \cdot (a_1 + a_n)}{2}$
A soma dos primeiros $n$ termos de uma PG é dada por: $S_n = \frac{a_1 \cdot(q^n - 1)}{q - 1}$
Fórmula lei de Força Elétrica: $F = k_e \frac{|q_1 q_2|}{r^2}$
