Differentiate sin(sin(sin x))

OpenStudy (cwrw238):

i've done it by i want it checked

OpenStudy (anonymous):

\[\frac{d}{dx}(\sin(\sin(\sin(x)) = \cos(\sin(\sin(x))) \times \cos(\sin(x)) \times \cos(x)\]

OpenStudy (cwrw238):

yup - thanx

OpenStudy (cwrw238):

you're pretty fast - it took me a while to figure that out

OpenStudy (anonymous):

How??

OpenStudy (cwrw238):

i used the chain rule

OpenStudy (anonymous):

Always remember: \[\frac{d}{dx}(f(x)) = \frac{d}{dx}(f(x)) \times \frac{d}{dx}(x)\]

OpenStudy (cwrw238):

- maybe its because i'm not too keen on calculus lol

OpenStudy (anonymous):

So \[\frac{d}{dx}(\sin(\sin(\sin(x)) = \cos(\sin(\sin(x))) \times \frac{d}{dx}(\sin(\sin(x))\] \[\cos(\sin(\sin(x))) \times \frac{d}{dx}(\sin(\sin(x)) \implies \cos(\sin(\sin(x))) \times \cos(\sin(x)) \times \frac{d}{dx}(\sin(x))\]

OpenStudy (anonymous):

\[\cos(\sin(\sin(x))) \times \cos(\sin(x)) \times \frac{d}{dx}(\sin(x)) = \cos(\sin(\sin(x))) \times \cos(\sin(x)) \times \cos(x) (1) \]

OpenStudy (anonymous):

\[\cos(\sin(\sin(x))) \times \cos(\sin(x)) \times \cos(x) \times \frac{d}{dx}(x)\] \[\implies \cos(\sin(\sin(x))) \times \cos(\sin(x)) \times \cos(x)\]

OpenStudy (anonymous):

One by one we have to take all the derivative..

OpenStudy (cwrw238):

yes - i think i just need some practice in these to speed me up

OpenStudy (cwrw238):

ty

OpenStudy (anonymous):

You are quite intelligent I believe.. Just a little more practice will give you command over this..
