Hi, What will be the period of the function: $\displaystyle f(x)=\left ( \sin x \right )^{\circ}$ Thanks. Last edited by skipjack; August 13th, 2018 at 08:28 AM.

What's the degree symbol for? And what do you think the period will be..

It was in a book. If it is zero, then period is indeterminate and if degree, then 2pi. Thx.

Did the book give $\displaystyle f(x) = \left (\sin x^\circ\right)$?

No, not this. Only the one which I posted.

Okay. In that case, it's a degree symbol (a zero looks slightly different) and the period is 2$\pi$.
