Question

diffrenciate with respect to x
sec(tanx)

Answer 1

sec(tan x).tan(tanx).sec^2x

Answer 2

can u give the method??? solve full question please!

Answer 3

Chain rule... and the 'hit list'.
First, identify the outermost function, the function that sorta 'contains' all the others... which is it?

Answer 4

cn u solve full question fr me

Answer 5

Of course I can...but then again... YOU have to do it... I'm just here to help you along... :)

Answer 6

pls hlp me!!! give me the full method and solution

Answer 7

Yes, I'm here to help you... but not do it for you. There's a difference :)
Now, please help me... help you.
What's the outermost function of
sec(tan(x)) ?

Answer 8

sorry, i didnt get ur question

Answer 9

Outermost... the one that contains all the others...

Answer 10

secx=secx*tanx

Answer 11

Let me just fix that...
\[\Large \sec(x) \color{red}\neq \sec(x)\tan(x)\]\[\Large \frac{d}{dx}\sec(x) = \sec(x)\tan(x)\]

Answer 12

Okay, good, so you know that the derivative of sec(x) is sec(x)tan(x)
So, part of the derivative of sec(tan(x)) would be
sec(tan(x))tan(tan(x))
okay?

Answer 13

kkk

Answer 14

Now, once you've gotten rid of the sec(x) what's the next function (the one that's immediately inside the sec() )?

Answer 15

i got it

Answer 16

You're sure?
Okay then.

Answer 17

tanx=sec^2x

Answer 18

So you multiply this to the sec(tanx)tan(tanx)

Answer 19

can i send u frnd request

Answer 20

All in good time.
