Equation

$$a^2 + b^2 = c^2$$

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}🔨$$

$$E = mc^2$$

$$\int_a^b f(x) , dx = F(b) - F(a)$$

$$\frac{dy}{dx} = ky$$

$$f(x) = f(a) + f'(a)(x - a) + \frac{f''(a)}{2!}(x - a)^2 + \frac{f'''(a)}{3!}(x - a)^3 + \cdots$$

$$x^2 + y^2 = r^2$$

$$\log_a(b) = \frac{\log_c(b)}{\log_c(a)}$$

$$e^{i\theta} = \cos(\theta) + i\sin(\theta)$$
