Prove that: `(cos e c(90^0+theta)+cot(450^0+theta))/(cos e c(90^0-theta)+t a n(180^0-theta))+(t a n(180^0+theta)+s e c(180^0-theta))/(t a n(360^0+theta)-s e c(-theta))`=2

Explanation

To prove the given expression:

\[ \frac{\csc(90^\circ + \theta) + \cot(450^\circ + \theta)}{\csc(90^\circ - \theta) + \tan(180^\circ - \theta)} + \frac{\tan(180^\circ + \theta) + \sec(180^\circ - \theta)}{\tan(360^\circ + \theta) - \sec(-\theta)} = 2 \]

we will simplify each term step by step.
