How to Evaluate a Definite Integral x^2-1 from x=1 to x=2 [Worked Example] Calculus

In this video I show you how to evaluate a definite integral.

In this example we're evaluating the definite integral of x^2-1 from x=1 to x=2.

I also show you how to graph the function in DESMOS so that you can approximate what your answer should be so that you can know if what you get is reasonable.

Hope this helps you.

Please let me know in the comments if you have any problems from Algebra I, Algebra II, Pre-Calculus, Trigonometry, Calculus, AP Calculus AB, AP Calculus BC, or AP Statistics that you'd like me to do a video on.
