Q 2 a )please please answer m understanding distance formula
Find the distance between the following pairs of points. Calculate correct to three
figures.
(a) (0, O , (-5, 12) (b) (4, (-4, 3)
Find the distance between the points P on the x-axis and Q on the y-axis, where OP?
OQ = 8 cm and O is the origin. Use distance formula to find the length PQ.
(b) The point Q has the coordinates (0, —4). Find the coordinates'dfthe
distance between P and Q is 5 units.
(a) Prove the distance between A(I, 2) and B(3, 8) is double the
(b) If the coordinates of the points A and B be (asin 0, —b cos 0) 0, bsin
prove that 0142 + OB2 = a2 +b2, where O is the origin.
• *c) Prove that the distance of the point (asin 0+bcos 0, acos O-bsinO) from
independent of the value of 0.
*A,) Find a if the distance of the point (4, 1) from the point (3, a) is
