1. The problem statement, all variables and given/known data i have to draw the graph of y=(sin(x)^2)/x^2 on matlab in interval [0,4pi] 2. Relevant equations 3. The attempt at a solution i defined x and y. >>x:[0:pi/4:4pi] but i can't write the equation in matlab fprm...i dont know where to put the dots and brackets. i tried: >>sin(x).^2./x.^2 and i just got a straight line, then i tried: >>sin(x.*x)./(x.*X) and i also got a striaght line but when i put the function onto the graphics calculator it gives like a mountain shape and i think that's write. so how do i type the function onto matlab to give the right graph? can someone please help me?
