Find the derivative of the following functions (it is to be understand that a,b,c,d,p,q,r and s are fixed non-zero constants and m and n are integers):
`co sec x cot x`

Explanation

Let `y=co sec x cot x`
`rArr(dy)/(dx)=(d)/(dx)(cosec x cot x)`
`=co sec x(d)/(dx)cot x+cotx(d)/(dx)co sec x`
`=co secx(-co sec^(2)x)+cot x(-co sec x cot x)`
`=-co sec^(3)x-co sec xcot^(2)x`
