Dear tutor @Math_Therapy, when this writer/(problem's composer) wrote
"Express the arc length in terms of . . . "
he / (or she), OBVIOUSLY, wanted to say " in terms of the arc angular measure ",
but, OBVIOUSLY, forgot (or did not know) these words.
I am able to read between the lines, as well as between the words, too . . .
I do it very easy; it is not difficult to me . . .
You can put this solution on YOUR website!
