$$\left({t}^{\mathrm{2}} +\mathrm{1}\right)\frac{{d}^{\mathrm{2}} {p}}{{dt}^{\mathrm{2}} }+\frac{{dp}}{{dt}}×\mathrm{2}{t}=\frac{{d}}{{dt}}\left({p}^{{t}} \right) \\ $$$${y}={p}^{{t}} \\ $$$${lny}={tlnp} \\ $$$$\frac{\mathrm{1}}{{y}}\frac{{dy}}{{dt}}=\frac{{t}}{{p}}\frac{{dp}}{{dt}}+{lnp} \\ $$$$\frac{{dy}}{{dt}}={y}\left[\frac{{t}}{{p}}\frac{{dp}}{{dt}}+{lnp}\right] \\ $$$${unique}\:{question}...{force}\:{the}\:{sleeping}\:{cell}\:{of}\:{brain} \\ $$$${to}\:{wake}\:{up}...{searching}\:{way}\:{to}\:{solve}... \\ $$ | ||
