the question is to find the area enclosed between the y axis, the line y=10 and the exponential curve using integration.

so first i need to switch the function around. f(x)=2e^x y=2e^x y/2 =e^x im not sure what i do next is correct. i get ln of both sides ln y/2 = ln e^x so

ln y/2 =x ln e ln y/2 =x (1) ln y/2 =x. i dont know how to integrate ln y/2 after this though i would find the definite integral of from 10 to 2.
