Question

$3 \: sec \: \alpha = 5 \: then \: find \: cosec \: \alpha - sin \: \alpha$
​

Answer 1

Step-by-step explanation:

$3 \sec\alpha = 5 \\ \sec \alpha = \frac{5}{3} \\ so... \\ \cos\alpha = \frac{3}{5} \\ then... \\ \sin\alpha = \frac{4}{5} \\ \csc \alpha = \frac{5}{4}$

hope my answer will help you...
