Differentiation of e

How to differentiate e^tanx?

first of all to differentiate e^anything = (Diff anything)*e^anything

so to differentiate e^tanx = (Diff tanx)*e^tanx = sec^2x*e^tanx

:)

btw, i couldn't remember what is Diff tanx = to, but i know how to sinx & cosx
so tanx=sinx/cosx Diff using quotient rule, get the ans within 30s :)

  1. Hi!

    I'd just really like to thank u all 4 setting up this blog. I find a lot of the tips useful, especially those 4 a-math.

    however could u also post up more qns with worked solutions up on absolute valued functions, rates of change and applications of integration(area under the curve)?

    i really could use some help with these topics. thank u so much.

  3. HI..

    btw,
    its diff(tanx)=sec^2(x), isn't it?

    Diff (tan x) = sec^2x READ as sec sqaure x ;)
