## How do you plot a sine graph in MATLAB?

MATLAB Sine Wave Plot

1. fs= 500e3;
2. f= 1000;
3. nCyl=5;
4. t=0:1/fs:nCyl*1/f;
5. x=sin(2*pi*f*t);
6. plot(t,x)
7. title (‘Continuous sinusoidal signal’)
8. xlabel(‘Time(s)’);

How do you generate sin in MATLAB?

in sine function in MATLAB it is always sin(wt). here frequency w is in radian/sec not f (in HZ) so w will give you the no. of the cycle. if you want to use the sin(2*pi*60*t) you can use the sind(2*pi*9.545*t).

### How do you graph a sine function?

To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called ‘sinusoidal’ after the name of the sine function.

How do you plot a 3 variable function in MATLAB?

1. f = @(x,y,z) x.^2+y.^2+z.^2-3*x.*y.*z ;
2. x = linspace(-1,1) ;
3. y = linspace(-1,1) ;
4. z = linspace(-1,1) ;
5. [X,Y,Z] = ndgrid(x,y,z) ;
6. F =f(X,Y,Z) ;
7. figure.
8. hold on.

## How do you visualize a function with two variables?

Functions of Two Variables Now there are two main ways to visualize such a function: a contour plot, or a two-dimensional picture of the level curves of the surface, which have equations of the form f(x, y) = c, where c is a constant.

How do you graph Sinx 2?

first draw sin x graph, and reflect the negative part of y(the part of sketch going below x axis) about x axis..after that the graph u obtain is y=|sinx| so make one last change, since for x=n(pie) the graph may seem non-differentiable , so make the curve smooth at the points..and voila! U have sin^2 x in front of u.

### How do you write sin 2?

Sin squared formula

1. ⁡ θ = 1 − cos 2 ⁡
2. ⁡ θ + cos 2 ⁡
3. ∴ sin 2 ⁡ θ = 1 − cos 2 ⁡

What is the graph of sine?

The graphs of functions defined by y = sin x are called sine waves or sinusoidal waves. Notice that the graph repeats itself as it moves along the x-axis. The cycles of this regular repeating are called periods. This graph repeats every 6.28 units or 2 pi radians.
