So the integral of 2 is 2x + c, where c is a constant. A "S" shaped symbol is used to mean the integral of, and dx is written at the end of the terms to be integrated<span>, meaning "with respect to x". This is the same "dx" that appears in dy/dx
</span>To carry out integration<span>, it is important to know the general power rule. It is the exact opposite of the power rule for differentiation. When we take the </span>integral<span> of the function, we first add 1 to the exponent, and then divide the term by the sum of the exponent and 1</span>
