MATHEMATICS CO-ORDINATE GEOMETRY Angles between Lines Parallel lines: The angle between parallel lines is 00 because they have the same gradient   Perpendicular Lines: Angle between two perpendicular lines is 900 and the product of their gradients is – 1. Hence, m1m2 = – 1 Examples: Show that the lines y = -3x + 2 ….  Read More

Length: 0 minutesAuthor: Mary Okoh

MATHEMATICS Differentiation Velocity and Acceleration Velocity: The velocity after t seconds is the rate of change of displacement with respect to time. Suppose; s = distance and t = time, Then; Velocity = ds/dt Acceleration: This is the rate of change of velocity compared with time. Acceleration = dv/dt Example: A moving body goes s ….  Read More
