Question

derivation of cosecx​

Answer 1

Answer:

You can prove the sec x and cosec x derivatives using a combination of the power rule and the chain rule (which you will learn later). When you have sec x = (cos x)^-1 or cosec x = (sin x)^-1, you have it in the form f(g(x)) where f(x) = x^-1 and g(x) = cos x or sin x......
