Homework Statement
Find the range ##y = \sqrt{\ln({\cos(\sin (x)}))}##

I used a graphing calculator to find the intersection between ##y = e^{x^2}## and ##y = \cos(\sin(x))##.
Which I get as ##(0,1)##. So the range is ##\{0\}##.
But I want to find the range without graphs and by analytical methods.
Thanks for help.
