WebIn general, we solve equations by isolating the variable; that is, we manipulate the equation to end up with the variable on one side of the "equals" sign, with a numerical value on the other side. The general process for isolation is, in a sense, undoing whatever had been done to the variable in the original equation. WebIan Pulizzotto. Yes this is because the integral is definite. For definite integrals, because the antiderivative must be evaluated at the endpoints and the results must be subtracted, the "plus C" terms would cancel out in the subtraction. This is why "plus C" does not appear in the answer for a definite integral. WebA symbol (usually a letter) that represents an unknown quantity.
