Question

Implicit differentiation and graphs

Answer 1

\(y = \sin x \)

differentiate w.r.t \(t\)

Answer 2

\(y = \sin x \)

differentiate w.r.t \(t\)

\(y' = \cos x ~ x'\)

Answer 3

you're given \(x' = 2\)
plug it

Answer 4

\(y' = 2 \cos~ x\)

fine ?

Answer 5

Yes

Answer 6

y'=2cos(pi/6)?

Answer 7

@ganeshie8

Answer 8

yes thats for a

Answer 9

Do i have to solve?

Answer 10

yes ofc u have to simplify it

Answer 11

y'=2cos(pi/6)
= 2*sqrt(3)/2
= sqrt(3)

Answer 12

similarly find b and c

Answer 13

for b:-

y'=2cos(x)

y'=2cos(pi/4)
= 2*1/sqrt(2)
=sqrt(2)

Answer 14

id let u work c :)

Answer 15

OK I will can i ask you a question

Answer 16

and yes, u need to remember those trig values

Answer 17

go ahead ask :)

Answer 18

how did you know it was equal to 2 sqrt 3/2

Answer 19

I just got a big decimal

Answer 20

good question :)
i just memorized them

Answer 21

we need to memorize few trig values before coming to calculus premisis

Answer 22

lol alright now i know why. i never took trig :P

Answer 23

I didn't know i needed it until after my drop/add period so i could not withdraw
