Solution: (ii) y = x2 cuts y = x(x2 − 1) in 3 places. (ii) Curves cross at only 1 point. x − 4) in 4th quadrant. = (x − 2)3 is a translation of + 2 in the x-direction of y = x3. and in 2nd and 4th quadrants. 2 points of intersection [At (0,0) the curves actually touch. They intersect in the second quadrant.]
Check your answer using simple geometry. Exercise 6: Find the area enclosed between the curves y = 4x + 5 , y = 5x + 4 and the x-axis. Exercise 7: Find the area between y = sin x and y = cos x between two successive points where the curves intersect. Exercise 7: This area = /4 7 /4 [sin x − cos x] dx
The curve C has equation y x= − −9 2( )2. a) Describe geometrically the three transformations that map the graph of y x= 2 onto the graph of C. b) Hence, sketch the graph of C. The sketch must include the coordinates of • … all the points where the curve meets the coordinate axes. • … the maximum point of the curve.

4.Spiral- The spiral is a curve that has a varying radius. It is used on railroads and most modern highways. It provides a transition from the tangent to a simple curve or between simple curves in a compound curve (Figure 3-2, View D). 1.2.0 Elements of a Horizontal Curve The elements of a circular curve are shown in Figure 3-3.
