Find the general solution values of `theta` for which the quadratic `(sintheta)x^(2)+(2costheta)x+(costheta+sintheta)/2` is the square of a linear function.

Explanation

To find the general solution values of \( \theta \) for which the quadratic

\[ (\sin \theta)x^2 + (2 \cos \theta)x + \frac{\cos \theta + \sin \theta}{2} \]

is the square of a linear function, we will follow these steps:
