What is the area bounded by the curves y = x^2 and y=the square root of x
do you know the interval where they intesect?
\[\int_{a}^{b}f-g~dx\]
Solve \[x^2=\sqrt{x}\] to find the endpoints of the integral.
I don't understand how to do this, I need help working this out so I can use this as an example for the rest of my work
this is the help ... define the interval, and integrate the difference of the functions inbetween
if you get a negative value at the end, drop the sign
\[\left|\int_{a}^{b}x^2-x^{1/2}~dx\right|\]
|dw:1372885866321:dw| You find the two points where the curves cross to determine the endpoints of the integral. The integral adds up all the infinitesimal rectangles from the function with the greater y value down to the function with the smaller y-value between the endpoints.
