Read the given information carefully and answer the given questions.
If $$p = X\cos \theta - Y\sin \theta $$,
$$q = X\sin \theta + Y\cos \theta $$ and
$${p^2} + 4pq + {q^2} = A{X^2} + B{Y^2}$$, $$0 \le \theta \le {\pi \over 2}$$.
If $$p = X\cos \theta - Y\sin \theta $$,
$$q = X\sin \theta + Y\cos \theta $$ and
$${p^2} + 4pq + {q^2} = A{X^2} + B{Y^2}$$, $$0 \le \theta \le {\pi \over 2}$$.
What is the value of $$\theta$$ ?
