Can you find me the first derivative of the Arctan(x² + x) equation?

 

f(x) = arctan(x²+x)

f'(x) = 1 / ((x²+x)² + 1) = 1 / (x²(x+1)²)

 

 

 

 Well done Twesterm, but the final result is 1/(x²(x+1)²+1), you forgot the 1 ;)

bah, forgot to copy it from paper to here :-p

 

 

do i even need to correct this?  it's clearly wrong.
