 * InterActivity **: Input a linear change of variable (with a positive derivative for now) and hit enter. You should be able to scale the function properly.
 * Example 1:** Using linear change of variable: u=3x-2 => du=3dx so factor between areas is "3".


 * Example 2:** Using linear change of variable: t=0.5x+1 => dt=0.5dx so factor between areas is "0.5".


 * Example 3:** Using non-linear change of variable: t=ln(x) => dt=dx/x


 * Example 4:** Using non-linear change of variable: t=x²+1 => dt=2xdx so factor between areas is ?
