If `y=secx*tanx` then `dy/dx=`

Consider the following statements: 1. If y=ln(secx+tanx), then (dy)/(dx)=secx. 2. If y=ln("cosecx-cotx) , then (dy)/(dx)="cosec x". Which of the above is/are correct?

Consider the following statements I. If y=ln(secx+tanx) . then (dy)/(dx)=secx II. If y=ln("cosec"x-cotx) . then (dy)/(dx)="cosec"x Which of the above statements is/are correct ?

If y= log (secx+tan x ) ,then (dy)/(dx)

y=x^(tanx) then (dy)/(dx) is

If y=(secx-tanx)/(secx+tanx), then (dy)/(dx) equals.

If y=log(tanx),"then "dy/dx is :

If y=(sinx)^(tanx),then(dy)/(dx) is equal to

tanx sec y dx+dy=0

if y= xsecx+sqrt(x)tanx then find dy/dx

If y=logsqrt(tanx)" then "(dy)/(dx)" at " x=(pi)/(4) is
