The equation E=mc2E = mc^{2} revolutionized physics.
Below is a more complex integral formula:
f(x)=∫−∞∞f^(ξ) e2πiξx dξf(x) = \int_{-\infty}^{\infty} \hat{f}(\xi)\,e^{2\pi i \xi x}\,d\xi f(x)=∫−∞∞f^(ξ) e2πiξx dξf(x) = \int_{-\infty}^{\infty} \hat{f}(\xi)\,e^{2\pi i \xi x}\,d\xiAnd you can continue writing normal text with more inline math like α+β=γ\alpha + \beta = \gamma right here.
