Definite Integration We could add together the area of individual strips, which we want to make as thin as possible…
Reflecting on above, do you think the following definite integrals would be positive or negative or 0? + 0 + 0 +0
Evaluating Definite Integrals We use square brackets to say that we’ve integrated the function, but we’re yet to involve the limits 1 and 2. Then we find the difference when we sub in our limits. ? ? ?
Evaluating Definite Integrals ? ? Bro Tip: Be careful with your negatives, and use bracketing to avoid errors.
