प्रश्न

Find the nth derivative of the following : eax+b 

योग

उत्तर

Let y = eax+b 

Then `"dy"/"dx" = "d"/"dx"(e^(ax + b))`

= `e^(ax + b)."d"/"dx"(ax + b)`

= `e^(ax + b) xx (a xx 1 + 0)`
= aeax+b 

`(d^2y)/(dx^3) = "d"/"dx"(ae^(ax + b))`

= `a."d"/"dx"(ax + b)`

= `ae^(ax + b) xx (a xx 1 + 0)`
= a2.eax+b

`(d^3y)/(dx^3) = "d"/"dx"[a^2e^(ax + b)]`

= `a^2"d"/"dx"(e^(ax + b))`

= `a^2e^(ax + b)."d"/"dx"(ax + b)`

= a2eax+b x (a x 1 + 0)
= a3.eax+b 
In genaral, the nth order derivative is given by
`(d^ny)/(dx^n)` = an . eax+b.
