hi

I need a little help with integrating:

f(x)=4/(x+4)^2

integrating f(x) from 0~1

4∫¹₀(x+4)^-2
= 4[-(x+4)^-1]¹₀
= 4(-1/5 + 1/4)
= 4(1/20)
= 1/5

I need a little help with integrating:

f(x)=4/(x+4)^2

integrating f(x) from 0~1

f'(x) = 4/(x+4)^2
f(x) = -4/(x+4)
Substitue x = 1, and x= 0 like you do in the integration like this:
The value = -4/(1+4) - (-4/(0+4))
= -4/5 + 4/4
= 1/5

Damn, someone beats me to it. Should have started earlier.

thank you very much

haven't done integration in a while =/
