Hello All, I am new to this forum, and was wondering if anyone could help me with a homework problem I am having. 1. Consider the Integral, int(h(x)dx)=c, integrated from lower limit "a" and upper limit "b". where "a" is unknown and 0<a<b, c>0, h(x)>0, a<=x<=b. Task: Develop a general expression for determining "a" by a Newton-Raphson procedure, assuming that b,c,h(x) are known. 2. Relevant equations I know I need to derive the NR equation below in order to solve for the unknown lower limit. A(p+1)=A(p) -[f(Ap)/f ' (Ap)] I am just not sure how to apply the integral of a function to the NR method. Any help will be greatly appreciated!
