How to integrate cosec 2x

1 answer:

8 0

Remember that -csc^2(x) is a known derivative; it is the derivative of cot(x).

Keeping that in mind, let's put a negative there, and then offset it with another negative, which can conveniently be placed outside of the integral. 

(-1) Integral ( -csc^2(x) dx ) 

Which evaluates to 

(-1) cot(x) + C 
-cot(x) + C
