Periodic Functions

By
                    What is a Periodic Function? If the function 𝑓(𝑥)  repeats it’s value after equal interval of x , then 𝑓(𝑥)  is said to be a periodic function of x and the equal interval of x , is known as time period of the function 𝑓(𝑥) .                                       𝑓(𝑥) = 𝑓(𝑥 + 𝑇) = 𝑓(𝑥 + 2𝑇 )=. . . . . . . . . . = 𝑓(𝑥 + 𝑛𝑇) =. . . . . Here T is known as the time period of the function. Types of Periodic Function : Sinusoidal Periodic Function:    A sinusoidal function is a function that is like a  sine or cosine  functions.  Sinusoidal functions  are a specific type of  periodic function . Period of  Sine  and Cosine is 2π.  Time Period of Sin (t) and cos (t) is  T = 2𝜋    Time Period of Sin (mt) and cos (mt) ...

Motion in Straight Line

By
Motion in Straight Line: Motion in straight line is defined as motion in one dimension (1-D). It is also known as linear motion. It can be participated in two parts - (i) uniform linear motion and  (ii) non-uniform linear motion Uniform Linear Motion: In this motion a body covers equal distance in equal time intervals i.e. velocity along the path is constant.  In this motion a body moves with a constant acceleration.  Non-uniform Linear Motion: In this motion a body moves with a variable velocity in a given interval of time. Equation of Motion with constant Acceleration: Consider that a particle has constant acceleration 'a'. It's initial velocity is 'u' and final velocity is 'v' after 't' time. Now acceleration can be written as: dv/dt = a    Particle covers 's' distance or displacement (since particle is moving along the straight line) in time 't'. From 1st equation- write equation 1st again- Displacement of Particle in nth second: ...

Operations with Vectors

By
Vector Addition:   C onsider that a man is walking on a path ABC (from A to B and then from B to C) as shown in the figure. In this case displacement AC vector can be written as the sum of the AB vector and BC vector.                                 AB + BC = AC                    this is known as the  triangle rule   of   vectors.                                     So, in the general case if we have two vectors a and b are positioned so that the initial point of one coincides with the terminal point of the other. Then, vector (a+b) represented by the third side c vector of the triangle, which is the addition of (a+b) vector  or we can say resultant vector of a vector and b vector.             ...
