Evaluating the integral of an absolute value function YouTube
The integral of an absolute value function is an integral where the integrand is an absolute value function. But what is an absolute value function? It's pretty simple: An absolute value function is a function in which the variable is inside the absolute value bars. Integrating an Absolute Value Z 4 jx3 5x2 + 6xj dx 0 There is no anti-derivative for an absolute value; however, we know it's de nition. jxj = x if x 0 x elsewise Thus we can split up our integral depending on where x3 5x2 + 6x is non-negative. x3 5x2 + 6x 0: x(x2 5x + 6) 0: x(x 2)(x 3) 0: After testing the intervals (1 ; Free integral calculator - solve indefinite, definite and multiple integrals with all the steps.

1 To expand on @davin's comment: Use the definition of the absolute value! The absolute value equals "the inside" when "the inside" is non-negative, and equals " (-) the inside" when "the inside is negative. Using the Fundamental Theorem of Calculus to evaluate this integral with the first anti-derivatives gives, ∫ 2 0 x2 +1dx = (1 3 x3 +x)∣∣ ∣2 0 = 1 3(2)3 +2 −( 1 3(0)3 +0) = 14 3 ∫ 0 2 x 2 + 1 d x = ( 1 3 x 3 + x) | 0 2 = 1 3 ( 2) 3 + 2 − ( 1 3 ( 0) 3 + 0) = 14 3 Much easier than using the definition wasn't it?

Question Video Evaluating the Definite Integral of an Absolute Value
Keywords👉 Learn how to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiati. Video Transcript. If 𝑓 of 𝑥 is equal to six times the absolute value of 𝑥, determine the integral from negative six to six of 𝑓 of 𝑥 with respect to 𝑥. In this question, we're asked to evaluate the definite integral of six times the absolute value of 𝑥. And we know a few different ways for evaluating a definite integral.
Video Transcript. Evaluate the definite integral between negative four and five of the absolute value of 𝑥 minus two with respect to 𝑥. For this question, we've been asked to evaluate the definite integral of a function, which we'll call lowercase 𝑓. This function is the absolute value or the modulus of 𝑥 minus two. Integrals of Absolute Value Functions Practice Problems 1) ∫3 0 |x − 2| dx Show Answer 2) ∫6 0 |2x − 4| dx Show Answer 3) ∫4 0 |x + 3| dx Show Answer 4) ∫4 0 |3x − 6| dx Show Answer 5) ∫4 −4 |x| dx Show Answer 6) ∫3 0 |x + 1| dx Show Answer 7) ∫4 −1 |3x − 5| dx Show Answer 8) ∫2 −1 |5 − x| dx Show Answer 9) ∫−3 −7 −|x + 5| dx Show Answer
Definite Integral with Absolute Value 2x 7 from 0 to 7/2 YouTube
Step 1 : To evaluate the integral, we first equate the given function to zero and find x intercept. Step 2 : The modulus function will always have the shape of V. Draw the graph. Step 3 : With the given interval, divide the integral into parts, then integrate it. Problem 1 : Solution : Let y = 5x-3 put y = 0 5x-3 = 0 x = 3/5 In this video I explained how to integrate a function with argument containing absolute values.
