Q4) Find the turning points and the local maximum and local minimum of the given function 5 +-x +6x+1 3 N A:Q6) (a) Sketch the region between the given functions (curves): y= 2x and y=x (b) Calculate the area between the given functions (curves): 1= 2x and y=x. A:Q9) Determining Moments of Inertia of a range of engineering components Refer to pages 7 & 8 of below link, and find the moment of inertia of cross-section of a structural member about the horizontal axis. The cross section is that of an upright triangle of height h equal to 2 m and base b equal to 1 m.
