Q1) Given that A = and B = , find the matrix such that , where is a 2 X 2 identity matrix
Q2) The coefficient of X in the expansion of is 3 times the coefficient of . find the value of n.
i somehow worked my way through and got r = -2. is there something wrong?
Q3) The equation of a circle is X^2 + Y^2 - 10X - 4Y + 25 = 0
Find the set of values of K if the circle touches the line Y = K.
I subbed in the value of K into the equation but i have 2 unknowns. so how?
Hope someone could help me with this! thanks! (:
