Consider this function y = f(x) on the domain (-co, co). f(x) = { √x sin() + 38 if x = 0 38 if x = 0 (a) If x 0, f'(x)= | |

Determine f ″ ( x ) for f(x) = sec x

Find the derivative of the function. f(x) = 2xarccos(x) – 2/1 – x² X 2arccos(x) + 2 O 2arc cos (x) – 2/VI – x² os (x) – 2//1– x² 2arc cos (x) – 2x//1 – x² 2arccos(x)

Evaluate the first derivative of the following functions: g(x) : = cosx – sinx f (x) = 4x²cosx g(y) = 3siny – ycosy f(x) = 3secxtanx f(x) = 2 cos Vx - = 2 cos vx
