Hi, it would be a great help if Mathsgroup members can
show me how to code the following problem in

Say I have a function defined as:
f[a_, b_] = Integrate[Sin[x] + 3, {x, a, b}]

I can find b with given constant=2 and initial
Initialvalue = 0;
s1 = FindRoot[f[0, unknown] == 2, {unknown,
x1 = Part[s1, 1, 2]

Now, using the x1 value obtained from FindRoot, I can
find x2:
s2 = FindRoot[f[x1, unknown] == 2, {unknown,
x2 = Part[s2, 1, 2]

How can i do it for n times (to get xn in a list form)
with given initial value as:
initialvalue= {initialvalue1,initialvalue2,

whereby each xi will get initialvalue[[i]]. 

Thanking you in advance
