Find the integral of a^(x) where a is a constant

Starting with ∫a x dx , We can re-write a x using logs as e ln(a)*x using some of their properties We use the substitution u = ln(a)*x (as such du/dx = ln(a)) allowing us to easily integrate e u with respect...

Solve the differential equation dx/dt=-6*x , given when t=0 x=7.

You start by seperating the variables giving, (1/x)*dx=(-6)*dt you then integrate both sides with respect to the variables, ln(x)=-6*t+c you then subsitute in the given conditions to find 'c', ln(7)=0+c ther...
