Question

if F(x)=tanx, then fprime(pi/6)=

Answer 1

Have you differentiated F(x) and then sub'ed \(\frac{\pi}{6}\) into it?

Answer 2

Do you know the derivative of tan(x) ??

Answer 3

i kno the differvative is secxtanx
but i dont know where to go frm there :/

Answer 4

Yes, than just replace x by pi/6..

Answer 5

(2\[\sqrt{3}\]/3 and \[\sqrt{3}\]/3

Answer 6

\[F'(\frac{\pi}{6}) = \sec(\frac{\pi}{6}) \cdot \tan(\frac{\pi}{6})\]

Answer 7

igot tht part

Answer 8

What is the value of :

\[\sec (\frac{\pi}{6})\]

Answer 9

2root3/3

Answer 10

Yes and what is for tan(pi/6) = ??

Answer 11

root3/3

Answer 12

Wait, derivative of tan(x) isn't it sec^2(x) ??

Answer 13

its not ?

Answer 14

\[\frac{d}{dx} \tan(x) = \sec^2(x)\]

Answer 15

thts y im getting the wrong answer

Answer 16

thank you

Answer 17

You were doing the derivative of sec(x)..

Answer 18

yea

Answer 19

\[\frac{d}{dx}\sec(x) = \sec(x) \cdot \tan(x)\]
It is okay and sorry from my side too, I also got confused..

And you are welcome dear..

Answer 20

ok idk how to combine the 2 radicals

Answer 21

Where ??

Answer 22

sec^2

Answer 23

\[F'(\frac{\pi}{6}) = \sec^2(\frac{\pi}{6})\]

Answer 24

yea

Answer 25

\[\implies \frac{2 \sqrt{3}}{3} \times \frac{2\sqrt{3}}{3} \implies ??\]

Answer 26

This is simple multiplication and division now...

Answer 27

i know but im not getting the right answer

Answer 28

4

Answer 29

What are you getting tell me first...

Answer 30

Its not 4...

You are missing something.

Answer 31

\[\sqrt{3} \times \sqrt{3} = ??\]

Answer 32

2 times 2=4
root3 times root 3= 3
4 times 3 =12
12 divide3 =4

Answer 33

12 divided by 3 ???

Are you sure in denominator it is 3 ??

Answer 34

im not too good with my unit circle

Answer 35

Dear, what will you get when you will square 3 ??

Answer 36

9

Answer 37

Check the colored things here :

\[\frac{2 \sqrt{3}}{\color{red}{3}} \times \frac{2 \sqrt{3}}{\color{red}{3}} = ??\]

Answer 38

9

Answer 39

Yes it is 12 divided by 9 and not 3..

So what will you get now ??

Answer 40

ohhhhhh

Answer 41

4/3

Answer 42

i was thinking addition

Answer 43

my mistake...srry if i took up yhur time

Answer 44

It is okay but be careful from next time...

These are called "Silly Mistakes..."

Ok, now concentrate more on new problems...

Answer 45

It is okay..

Answer 46

thanks a lot :)))
