1. The problem statement, all variables and given/known data Let g'(x)=-17x16* sin(Ax9) - 9Ax25*cos(Ax9) g(1)=143/9 Where A is a real number such that tanA=1/sqrt(80), 0<A<pi/2 Find g(0) 3. The attempt at a solution I was able to get the antiderivative of g'(x), so that: g(x) = -x17*sin(Ax9) I got A=6.3794 degrees. BUT, I don't get g(1)=143/9 What am I doing wrong? Did I assume wrong that the g'(x) was created by the product rule?
