Signal syntax and plotting

i need to plot the following signal

as i'm relatively new to MatLab. i've got no idea on how i'm supposed to write it.

i would like some help/assistance on how to do the aformentioned task and how to solve signal-plottying/syntax in general.

i've googeled a bit, but so far i've not been able to understand how to do it.

anny direct help or reference to resources on "how to" would be greately appreciated. thanks in advance.

first you must understand the equation you need to solve, then know how to write it with the right syntax and finally plot the required results.

i think the V is the max value and its constant so i will define it as vaule

V_max=10;      % max value of V is 10

then the value of t i suppose it value from 1 to 90 with step of 1

t=1:1:90;

and easily we can write the equation

vo=(2+0.1961*cos(0.1*t-0.1961)+0.003998*cos(15*t-1.5375)+0.001667*cos(300*t-1.5691))*V_max;

and plot t with vo

plot(t,vo)

plot function syntax form here

there are more than function to plot data according to data type and the graph shape

To clarify V just stands for "Voltage" and the "t" is time.

alrighty. i'll try to implement something, seems so simple above, thanks :)

i'll update on how it goes.
