find the area of the region bounded by y=4x, y=x^3, x=0 and x=2 Check this on paper, but in my mind I see the differential area (x^3-3x)dx integrate that from 0 to 2 y=4x and y=x^3 intersect when x=-2,0 and 2 the vertical boundaries are x=0 and x=2, so the area is the integral...

differentiate y=ln(x^5-e^x) Please show the steps in solving change it to y=ln u dy/dx= dy/du * du/dx and of course, dy/du= 1/u I will be happy to critique your work. 1/4x * 4/4x = 4/x Is this correct?

calculus
Differentiate y=lnx You ought to have this memorized. y'=1/x for y= ln x dy/dx = 1/x This is the most basic and fundamental of log derivatives. If you are studying Calculus, and the topic is logs, I fail to understand why you asked that question. IS there a website that ca...
