Question: Plotting an AM waveform

I am in the process of trying to learn Maple. As an exercise I am trying to plot an amplitude modulated waveform. No problem plotting the waveform of the carrier and the modulating signal but for some reason (user error on my part) I can't plot the combined waveform y given by. 

y = [1 + M*cos(2*Pi*f__m*t)]*A*sin(2*Pi*f__c*t)

Where the following values have been set M = 0.5, A = 1, f_m = 2, f_c = 10.

Plotting y using the following

plot(y, t = 0 .. 1, title = "Graph of Carrier", labels = ["time (seconds)", "Amplitude (Volts)"], color = red);

Gives the following error. Having tried various combinations of variables, values, single parameter functions etc I need a pointer as to where I am going wrong. 

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct
What I am expecting is a graph similar to the below derived in Excel? My version of Maple is 2023.2
