continuous signal to discrete

hello, im quite new to using matlab. im trying to convert the signal 𝑥(𝑡)=2sin(50𝜋𝑡)+1.5sin(2500𝜋𝑡)−3cos(6000𝜋𝑡) from continous to discrete then plot it. could anyone help please?

You didn't really describe what you tried and where you got stuck...how about a simplified example that has all of the building blocks and then you can apply the knowledge to your equation?

x = linspace(0,10,1000);
y = sin(x*2*pi)*3 + cos(x*pi);
plot(x, y)

MATLAB has some great documentation, you can find just about all of it by searching google:
