| trouble with few cal questions
help would be greatly appreciated.
A) find areas of the regions bounded by f(x) = x^2 and g(x) = (x^2/2) +2
B) find areas of the regions bounded by f(x) = x^2 and g(x) = (1 - x^2)
C) area of graph of f(x) = sqrt(x), the horizontal axis, and the vertical axis through (2,0)
lastly, i have no idea how to approach
Prove that int(x^3dx) from 0 to b = (b^4/4), by considering partitions into n equal subintervals, using the forumula for summation i=1 to n of i^3.
