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
Show that the four points A,B, C and D with position vectors:
respectively are coplanar.
Let,
are coplanar if
= - 4(15) + 6(21) - 2(33)
= - 60 + 126 - 66
= 0
are coplanar.
Therefore, Points A, B and C are coplanar.
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.
