1.	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`
Answer» 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`
