Hello,
sin thita=cos thita
this possible only at the value of thita= 45
The value of cos and sin will be same at the thita value of 45 degree.
at thita=45 the value of sin45= 1/ square root 2 and cos45 value is 1/square root2
so for thita= 45 the value of cosec is square root2
hope this helps
Question : What is the value of the expression: $\sin A(1+\frac{\sin A}{\cos A})+\cos A(1+\frac{\cos A}{\sin A})$?
