How do I find an anti-derivative that is the inverse of the sum rule? (f+g)'(x) = f'(x) + g'(x)?
dont understand... there is sum rule for integrals too. its the same
trying understand the example here: http://ocw.mit.edu/courses/mathematics/18-01sc-single-variable-calculus-fall-2010/part-c-mean-value-theorem-antiderivatives-and-differential-equations/session-37-antiderivatives/MIT18_01SCF10_ex37prb.pdf
sorry, anti-derivative rule...
\[\int (a(x)+b(x))dx=\int a(x) dx+\int b(x) dx\]
