Question 43
simplify $$\frac{cot (90^\circ-\theta) sin(180^\circ-\theta) sec(360^\circ-\theta)}{tan(180^\circ+\theta) sec(-\theta) cos(90^\circ+\theta)}$$
Solution
$$\frac{cot (90^\circ-\theta) sin(180^\circ-\theta) sec(360^\circ-\theta)}{tan(180^\circ+\theta) sec(-\theta) cos(90^\circ+\theta)}$$
$$\frac{cot (90^\circ-\theta)$$ = tan(\theta)
$$sin(180^\circ-\theta)$$
$$sec(360^\circ-\theta)$$
$$tan(180^\circ+\theta)$$
$$sec(-\theta)$$
$$cos(90^\circ+\theta)$$
