Absolute value integral

In this video, I showed how to compute the definite integral of an absolute value function using the even or odd nature of the function for speed.

    I LOVE this problem. I always spent a lot of time on absolute value in my pre-calculus class! Every time I watch you, I miss teaching so much!

    ... A good day to you friend Newton, Again I saw a perfectly executed presentation on an absolute value definite integral, I followed exactly the same strategy (graphs are great tools in this case), as if we had the same math teacher in the past (lol). A small comment I want to make regarding the sign analysis between - 4 and 4 is, we know that - 1, 0, and 1 are zeros, and that there aren't any asymptotes present, so we know that at these points there will be a sign change left and right, this means that we only need to do one sign calculation, at least this is what I did ... thank you again master Newton for a very clear presentation delivered with great enthusiasm ... Take care my friend, Jan-W

    Thank you for explaining. If we use the (given formula) = 2 ∫(0~4) |x^3-x| dx, it is -2 ∫(0~1) (x^3-x) dx + 2 ∫(1~4) (x^3-x) dx = 2×(1/4) + 2(56+1/4), and the calculation is a little easier.

    Here is a nice way of doing this without even making the chart, although you need the cut-off points that you found. Over each interval that you found, I integrate x^3-x for all of them. To make sure that you get the correct result, take the absolute value of each integral. That does make it faster.

    I integrated and multiply it by 2 the answer 112 . Why I didn’t get 113 ?

    Your integration should give 56 ½ before you multiply by 2

    I also got 112 for the "fast way" (which took me more time than the "long way"!). I found out I needed two integrals of x^3 - x. First from 1 to 4 giving 56.25 and then from 0 to 1 giving -0.25. Now, to account for the absolute value nature of the problem that negative area has to be flipped over the x-axis thus becoming+0.25. So finally 2 ( 56.25 + 0.25) = 113. Whew. Best wishes to all for a happy New Year 🎉

    | x^3 - x | being an even function Given integration equals to integrate [0, 4 ] ( x^3 - x) dx =2 ( x^4 /4 - x^2/2 ) = 2 * 4^3 - 4^2 = 4^2 ( 8 -1) = 112

    You forgot that x^3 - x is negative from 0 to 1 :) So you need to split the integral at 1

    Yeah but you have to integrate -(x^3 - x) for the interval from 0 to 1, because of the absolute value operator
