If `y=sec^(-1) x`, then `dy/dx` is

If y=sec x^(@) , then (dy)/(dx)=

If y=sec(tan^(-1)x), then (dy)/(dx) at x=1 is equal to: (1)/(sqrt(2))(b)(1)/(2)(c)1(d)sqrt(2)

If y=sec(tan^(-1)x), then (dy)/(dx)atx=1 is (a) (cos pi)/(4)(b)(sin pi)/(2)(c)(sin pi)/(6)(d)(cos pi)/(3)

if y=sec(tan^(-1)x)then(dy)/(dx) is

If y=5^(x) sec^(-1)x,"then " dy/dx=

If y=sec(tan^(-1)x) ,then (dy)/(dx) at x=1 is equal to (1)(1)/(2)(2)1(3)sqrt(2)(4)(1)/(sqrt(2))

If y= sec (tan^(-1)x)," then "(dy)/(dx)" at " x = 1 is equal to
