Question 601190: the expression (cot x)(sec x) is equivalent to ?
(1) sin x
(2) cos x
(3) csc x
(4) sec x
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
cot(x)*sec(x)

(cos(x)/sin(x))(1/cos(x))

cos(x)/(sin(x)cos(x))

1/sin(x)

csc(x)

So cot(x)*sec(x) simplifies to csc(x)
