Unformatted text preview: hat up to adding a constant to it, this is the only function that will work as an antiderivative. The notation that we will use to indicate that we are finding the antiderivative of a function is called an integral sign. It looks like ∫ (kind of an elongated “S”, which we will see a connection to in a later section). Similar to when we found derivatives, we need to know with respect to which variable we are working. So this integral sign ALWAYS comes paired with something of the form dx , indicating that x is the variable we are interested in. So, for example, the antiderivative of the function 2 x , with respect to the variable x is written as ∫ 2 x dx . The act of finding the function to which this is equal is called antidifferentia...
