uestion Find y" of the function y = sin(sin(20)) O y" = -4cos?(20) sin(sin(20)) - 4 sin(20) sin (0) O y" = - cos2(20) sin(sin(20)) - 4 sin(20) cos(sin(20)) O y" = cos?(20) sin(sin(20)) - 4 sin(20) cos(sin(20)) O y" = -4 cos? (20) sin(sin(20)) - 4 sin(20) cos(sin(20)) Question What is the Riemann sum to find an expression as a limit for the area under the graph of f(x) = \\sinx. OKEST. Do not evaluate the limit. A = lim 1-too sin ( ) . n A= lim LVsin ( ) . i O A = lim > sin(2). O A = lim > sin(#)
