MathJax
Here are some examples of MathJax. $$\Delta L=\alpha L_0\Delta T$$ $$Q=mc\Delta T$$ $$Q=Lm$$ $$pV=nRT-NkT$$ $$dE=dQ-dW$$ $$e=\frac{W_{out}}{Q_{in}}$$ $$W=\int pdV$$ $$\Delta S=\int \frac{dQ}{T}$$ $$\epsilon \le 1-\frac{T_L}{T_H}$$ $$\frac{dQ}{dT}=kA\frac{T_H-T_C}{L}$$ $$\frac{Q_C}{W}=COP$$ $$F=\frac{Gm_{1}m_{2}}{r^{2}}$$ $$T^{2}=\frac{4\pi^{2}}{GM}r^3$$ $$U_g=-\frac{Gm_1m_2}{r}$$ $$x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$$ $$\mathfrak{MathJax\;test}$$ $$\mathtt{MathJax\;test}$$ $$\mathscr{MATHJAX\;TEST}$$ $$\mathcal{MATHJAX\;TEST}$$ Reference: click here
