asked on # Question in Derivative and limits substitution

I am going through the solution of a problem and i dont understand how he got the values for theita ( see attachment)

0<theita<1.3694

obviously after the transformation of X as a function of cos Theita , there is some limit transformation as well.

Any input would be appreciate it.

let me post the question and complete solution Ozo
