I do not understand. I am going to lunch. Will check when I get back but another teacher will probably see it.
as x approaches 3.141593/4
4 not r, fingers are not cooperating
4 not r, fingers are not cooperating
sin x as x--> pi/4
Do not need a limit as far as I know
45, 45, 90 triangle 1,1,sqrt2
sin pi/4 = 1/sqrt 2 = sqrt 2/2 = 2^(1/2)/2
which is B
