DISPLACEMENT TIME GRAPH

Image
 DISPLACEMENT  TIME GRAPH The displacement   time graph is a graph that selects the axes of time for the horizontal axis and the displacement   for the vertical axis and draws for the motion of an object. The slope or gradient of a displacement time graph is the velocity Velocity is the rate of change of displacement. if slope is inceasing, velocity is increasing, accelerating if slope is decreasing, velocity is decreasing, nagative acceleration.

integration using trapezoidal rule

Image
  trapezium rule is a method to find an area of a graph for a given function. this rule can be used to obtained aproximation for given intragration, when it is defficult to calculate the value of integration mathematically. since the graphical meaning of the integration is area of the given graph this method is vary useful in integration, some functions are hard to integrate but graphs can be drawn for any given function. formula of trapezium or trapezoidal rule can be given as,  this a one method to find approximation value for area of a graph as well as solution for numerical integration following video may useful to watch regarding trapezium rule. when no of stripes are high accuracy of the integral is high.  https://youtu.be/3FOQ2gcpJ0M
