Use your calculator to solve the equation sin(x) - ln(x) = 0 over the interval [0, infinity). Make sure you're in radians.

I started by doing sin(x) = ln(x), then I said e^(sin(x)) = x. But I wasn't sure how to get x outside of the sin part. Could I get some hints?

Thanks so much in advance!

well a simple solution is graph both curves and looks for points of intersection... 

and that will give you a good starting point as to what values of x to try

I think you'll find there is only one point of intersection... you can use this site to graph them easily https://www.desmos.com/calculator
