(b) Compute the following number ¹76. (1+ + cos +isin

b) Differentiate the function below with respect to x. sin(-5+x) 4-8x f(x) = Note: = In Text mode the correct syntax is, say • In Symbolic mode the correct syntax is, say (6cos(5+6x)*(4+6x)-6sin(5+6x))/(4+6x)^2. Take note of the outer brackets in numerator. 6 cos(5+6x)+(4+6x)-6 sin(5+6x) (4+6x)2 ƒ'(x) =
