Question 471913: Could anyone help on this question i asked some time back but still i haven't got no answers
The position vectors of points A and B with respect to the origin O are given by
OA = i +3j +3k
OB = -4i + 5j +3k
Show that cos(AOB) = (4/root38)........i managed this bit
Hence or otherwise find the position vector of the point P on OB such that AP is perpendicular to OB
By putting 10^x = m show that the solution to the equation
(10^x + 10^-x)/(10^x - 10^-x) = k is x = 1/2log[(k + 1)/(k-1)]
Hence show that x = log2 + 1/2log3 - 1/2 when k = 11
