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 :)
Hi,
I'm Ai Ling. I enjoy coaching students who have challenges with
understanding and scoring in 'O' Level A-Maths and E-Maths. 
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.

StefAnIe: all those qns up here are from students.
We answer to what you all aren’t sure. We don’t answer to everything unless a student finds it challenge.
So whichever topic you find challenging, send us a qn to askalwayslovely@gmail.com
those who ask the particular qn will be guided through the step.

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

Stepfanie: Pls send me the qns you have challenges with.

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