Differentiate the following functions with respect to `e^(a x)secxtan2x`

Text Solution

Verified by Experts

Let `y=e^(a x)secxtan2x`
`(dy)/(dx)=d/(dx)e^(a x)secxtan2x`
`=d/(dx)(e^(ax))(sec x*tan 2x)+d/(dx)(sec x* tan 2x ) (e^(ax))`
`=e^(ax)[asecx*tan 2x +sec x*tanx *tan2x +2sec^2 2x sex x]`
`=e^(ax) sec x[atan 2x +tan x tan 2x +2 sec^2 2x]`
