math help. math iteration if you have a function. and you plug in an iteration, why does it sometimes converge, and why does it diverge? what makes it converge/diverge? for example... a sin graph. or a tan graph. if it has asinx. and a=1 while x =1 it would be sin1= answer sin (answer) = answer 2. but if you change the exponent in front, to say, 2sinx = answer.. if you repeat this iteration, it diverges, why?
