The absolute value (or modulus) of a real number is the corresponding nonnegative value that disregards the sign. For a real value, a, the absolute value is: a, if a is greater than or equal to zero. -a, if a is less than zero. abs(-0) returns 0.0. I know that to find the absolute value of a function, $$\frac {1} {b-a}\int^b_af (x)\mathrm {d}x$$. This is actually kind of intuitive. The problem is I don't know how to to find the average of the absolute value of a function. This would be fun to work out on my own, but I might use it on a test in the imminent future, I'd like to know.If you get an Integral object back, that means it couldn't evaluate it. The only thing that might help is rewriting the integrand in a way that SymPy can recognize. Looking at this issue, it looks like a workaround is to rewrite it as Heaviside: In [201]: z = symbols('z', real=True) In [202]: a = integrate(abs(z).rewrite(Heaviside), (z, -1, 1))Our expert help has broken down your problem into an easy-to-learn solution you can count on.

This is typically done by splitting the integral into two separate integrals split based on the x value of the the vertex. And then evaluating the integrals of each of the 2 line segments depending on the intervals of integration.The integral of 1/x has absolute value because the function 1/x is not defined at x=0. When taking the integral of a function, we are finding the area under the curve. Since the function is undefined at x=0, we need to take the absolute value in order to account for the area on both sides of the y-axis. 2.Our expert help has broken down your problem into an easy-to-learn solution you can count on.

The absolute value of a Riemann integrable function is Riemann integrable. 4.Thus, if you need areas under the x-axis to be negative, you don't really need to break up the integral. If you need the area under the x-axis to count as a positive area, then you need to break it up. Example: ∫ sin x dx over x = −π to π. This integral obviously equals 0, if areas under the x-axis are counted as negative.Equality of absolute values of complex integrals. Ask Question Asked 11 years, 5 months ago.
