plot 278.15 + 5 * sin(2*pi*t/24) in matlab

To plot the function 278.15 + 5 * sin(2*pi*t/24) in MATLAB, you can follow these steps:

1. Define the range of t values over which you want to plot the function. For example, if you want to plot the function for t values ranging from 0 to 24 (assuming the function is periodic over 24 hours), you can define t as follows:

main.m
t = 0:0.1:24;
14 chars
2 lines

This will create an array of values ranging from 0 to 24 with a step size of 0.1.

2. Evaluate the function for the defined t values. In MATLAB, you can use the element-wise operations to perform the calculations. For example:

main.m
y = 278.15 + 5 * sin(2*pi*t/24);
33 chars
2 lines

This will create an array y containing the function values corresponding to each t value.

3. Plot the function using the plot function. The plot function takes in the t and y arrays as inputs and generates the plot. For example:

main.m
plot(t, y);
12 chars
2 lines

4. Customize the plot if desired by adding labels, titles, legends, etc.

Here is the complete code snippet to plot the function:

main.m
t = 0:0.1:24;
y = 278.15 + 5 * sin(2*pi*t/24);
plot(t, y);
xlabel('t');
ylabel('y');
title('Plot of 278.15 + 5 * sin(2*pi*t/24)');
131 chars
7 lines

By running this code, you will obtain a plot of the function 278.15 + 5 * sin(2*pi*t/24) over the range of t values specified.
