# My Math Notes You can write **text** and inline math like $E = mc^2$ or display math: $$\int_{-\infty}^{\infty} e^{-x^2}\, dx = \sqrt{\pi}$$ ## Quadratic Formula The roots of $ax^2 + bx + c = 0$ are: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ ## Euler's Identity $$e^{i\pi} + 1 = 0$$ ## Matrix Example $$A = \begin{pmatrix} 1 & 2 \\ 3 & 4 \end{pmatrix}$$ Start editing on the left to see the live preview update!
