Question

Let \(f (x) = \sin (11 x)\). What is the fourth derivative of \(f (x)\)?

\(\frac{d^4}{d x^4} \sin (11 x) =?

Answer 1

11^4 sin(11x)

Answer 2

kindly explain it too

Answer 3

\[11^4 \sin(11x)\]

Answer 4

explain

Answer 5

what is \[\frac{d}{dx}\sin(ax)\]equal to?

Answer 6

i dont know

Answer 7

o yes acos(ax) right?

Answer 8

yes!

Answer 9

so what is\[\frac{d}{dx}a\cos(ax)\]equal to?

Answer 10

-a^2sin(ax)?

Answer 11

yes :-D

what is \[\frac{d}{dx}-a^2\sin(ax)\]equal to?

Answer 12

ok ok i get it thanks :)
