y = mx  and y = mx + c.
where m is slope (or gradient) and c is y intercept of  straight line.

Matlab code:

clc;         % Clear all input and output 

clear all; % Clear all variables 

close all; % Close all figures.

Basic trigonometry function

Matlab program to plot trigonometry function sine wave, cosine wave, tangent wave, cosec wave, etc. This is an example. You can plot other trigonometry function similarly.

Matlab code: 

clc;clear all;close all;
t=0:.2:15; % Time axis
% GENERATION OF SINE WAVE

Basic arithmetic operations
