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 (cosec x -cotx) ,then (dy)/(dx)

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

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

If y=(secx+tanx)^(cotx) then find (dy)/(dx)

If y=secx*tanx then dy/dx=

If y = tan^-1(secx+tanx) , then find (dy)/(dx) .

If y=(tanx+cotx)/(tanx-cotx)," then: "(dy)/(dx)=

If y=log(secx) , then (d^(2)y)/(dx^(2)) is :
