Homework Statement
I have a physics problem, but the math part is where I am getting stuck. I have to use the iterative method, which I understand, but I can't seem to get the correct result. My problem is that I have to plug the value of x=1.9195 into an equation f1(x)=(x/10)(x+3). I get a value of 0.9443 for f1(x). I then take that f1(x) and plug it into x=arcsin(f1(x). I am supposed to get something close to 1.9 for the new 'x' but when I do this, I get 1.2. This is strange to me because the sin of 1.9195 is 0.94 but the arcsin of 0.94 is 1.22 instead of 1.9195. Can anyone clear this up for me?
