If A, B, C are three non- collinear points with position vectors respectively, then show that the length of the perpendicular from C on AB is
Let ABC be a triangle and let be the position vectors of its vertices A, B, C respectively. Let CM be the perpendicular from C on AB. Then,
Area of triangle =

Draw a rough sketch of the curve and find the area of the region bounded by curve y2 = 8x and the line x =2.
Sketch the graph of y = |x + 4|. Using integration, find the area of the region bounded by the curve y = |x + 4| and x = – 6 and x = 0.
