I have an exercise that requires me to plot a function of y=x^2 from 0<=x<pi/2 what would be the right approach for this?

Is it a limit that you want to calculate approaching (pi/2)^2?

There are different ways to display a graph as you are asking, one of the most basic ones being
1. define the base vector
step=0.01
x=[0:step:pi/2]
2. define the function
y=x.^2;
3. display
plot(x,y)
grid on
comments:
- note the element wise operation implemented with the dot preceding the operator with '.^'
- plot has many optional fields, check MATLAB help for plot
- the smaller the step the higher the resolution
- grid on is also optional
- the figure window has a marker that can be used for quick checks
- ; at the end of a command line prevents MATLAB command window showing execution
if you find these lines useful would you please mark my answer as Accepted Answer?

You can use ezplot or fplot:
y = @(x) x.^2;
figure(1)
ezplot(y, [0, pi/2])
grid
figure(2)
fplot(y, [0, pi/2])
grid
