Hello everyone. I have the TI-nspire CX CAS and I need some help plugging in numbers.

I was wondering how to solve the function "0=x(sin(x))-(cos(x)" on the interval [0,4]. I need to find the precise points, not a graphical analysis. I can't seem to find any button that allows me to specify an interval. Do any of you know how to solve this? Thanks!
