Math Help - Integral - Exact Value

1. Integral - Exact Value

PROBLEM SOLVED!!!

hah thanks

Hi there,

I've got this Question , but im unsure of how to find the exact value... heres the info:

Find the Exact Value of ... the integral e^(x/2) dx from 0 to 2.
right so find the integral...

[ 2e^(x/2) ] from 0 to 2

i can work out from my calc.. that the value is 3.4365.. but not the exact value...

and the answer is 2(e - 1) which = 3.4365...

but i have no idea how you'd get the exact value.. ?
2(e - 1) is the exact value

3. .............

haha thanks for the quick reply..

yeah im tripping...

problem solved...

e^0 = 1

2 x 1 = 2...

2e - 2 ... hahah

ahh im an idiot.. ;-) thanks again
