I am going through the solution of a problem and i dont understand how he got the values for theita ( see attachment)<br />
<br />
0&lt;theita&lt;1.3694<br />
<br />
obviously after the transformation of X as a function of cos Theita , there is some limit transformation as well.<br />
<br />
Any input would be appreciate it.<br />
