First, you use the substitution u=1+e^x which implies that du=e^x dx. Then, you factorise e^3x = e^2x e^x and replace e^x dx with du. Then by re...

First, use the substitution u=e^x (which implies dx=du/u) to make the integral ∫6/(u*(u+2)))du. Next seperate the fraction using partial fractions and expand to form 3∫1/u du - 3∫1/(u+2) du. Next integrat...

The measures that government might use to restrict the monopoly power of supermarkets would be introducing competition policy like for instance introducing new entrant into the market so not only one firm...

As chain length increases, the boiling/melting point of hydrocarbon compounds increases. This is because whether a compound will change state from liquid to gas (boil) or not, depends upon the intermolecu...
