Find the derivative: 1 f (u) =  3 u + u 4. Find the derivative: r = 3 cos() 5. Find the derivative: x= 2 + t  t2 t3  3t + 1 6. Find the derivative: y= x2 + 3x  1 7. Find the derivative: v = cos3 u 8. Suppose that the point (4, 5) is on the graph of y = f (x) and that the derivative of f (x) at x = 4 is 11. Give an equation of the tangent line to y = f (x) at the point (4, 5). 9. Find q . q = 3 sin 1t 10. Suppose that x2 y  xy 2 = 2x. Find y at the point (x, y) = (3, 1). ...
