$\frac{dT}{dt}=k({M}^{4}-{T}^{4})$

where k > 0 is a constant. Show that the general solution of Stefan's equation is

$\mathrm{ln}|\frac{M+T}{M-T}|+2{\mathrm{tan}}^{-1}(\frac{T}{M})=4{M}^{3}kt+c$

where c is an arbitrary constant.

The students today that are looking for Calculus problems and answers online have way more luck than they would have even a few decades ago. However, one thing stays in common: it is not enough to find your answers and write them down for equations or trigonometry problems. It takes time to learn these rules, which is why Calculus and Analysis are so complex for most people. Do not let Calculus become another nightmare for you because you can look through the questions and answers and learn by example.
