I was given a problem by my friend Prosenjit Basak. The problem is : (sin(sin(sin x)))=(cos(cos(cos x))),then what is the value of x?Please explain the matter.
What matters most is what you do,rest all are TRASH.

Re: Problem of a problem
For example, let $x=45^\circ$
Then $\sin x=\dfrac {1}{\sqrt{2}}$
And $\sin (\sin x))=\sin \left (\dfrac {1}{\sqrt{2}} \right )^\circ$
I hope it's clear now.
Then $\sin x=\dfrac {1}{\sqrt{2}}$
And $\sin (\sin x))=\sin \left (\dfrac {1}{\sqrt{2}} \right )^\circ$
I hope it's clear now.
Re: Problem of a problem
It is most probably supposed to be in radian, as $\sin 45^\circ = \frac 1 {\sqrt 2}$, not $(\frac 1 {\sqrt 2}) ^\circ$Phlembac Adib Hasan wrote:For example, let $x=45^\circ$
