This is approximately the method I used with a TI Voyage 200, doing the first derivative and finding its positive root simultaneously in one entry. The Zeros function on the Voyager 200 (and TI-89T) allow bounding the domain. Your "x" is in radians. I will have to try how you did this and find where the menu system has the functions you used. Part of my challenge has been wandering around through the menus.

Thanks
