Homework Statement
Calculate the following integral with partial integration:
\int\frac{1 - x}{(x^2 + 2x + 3)^2}dx
The Attempt at a Solution
I guess you need to write the integral in easier chunks but I still fail every time.
Yes, I know what they mean, but I didn't know where to start.
So Δf should be:
Δf = (3.2 - 2.1)/(3.2 + 2.1) - (3 - 2)/(3 + 2)
Δf = 1.1/5.3 - 1/5
Δf = 0.007547...
And df should be:
df = ((2y)/(x+y)^2)*dx + ((2x)/(x+y)^2)*dy
Are my attempts correct ?
Homework Statement
f(x,y) = (x-y) / (x+y)
Calculate Δf and df for the change of point (3,2) to point (3.2, 2.1)
