Question

If A and B are two matrices of order 3 such that AB = 0
and A^2+ B = 1, then tr.(A^2+ B^2) is equal to

Answer 1

Step-by-step explanation:

A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
