please find the errors in the script

    d = 10;
    f=linspace(0,10^9);
    k = 0 : 0.01 : 10;
    x={cos(k.*d)+((111.0)./(2.*k))}*{(sin(k.*d))};
    Y=ceil(x);
    subplot(121),
    xlabel({'frequency','(in GHz)'})
    ylabel({'RHS of the equation','([cos(k*d)+(111.11/2k)*sin(k*d)])'})
    plot(f,Y);

@ per isakson:---> I am getting an error showing:-

Undefined function 'mtimes' for input arguments of type 'cell'.

That error is due to the fact that you enclosed the expression for x in {}, which makes it into a cell array. (It is not just like an extra set of parentheses.)

You also missed a spot using ".*" instead of "*'.

Finally, you were plotting against f against Y, which were different length vectors. I plotted k against Y instead, and the whole code runs now, but I am not sure it is what you intended.

d = 10;

f=linspace(0,10^9);

k = 0 : 0.01 : 10;

x=(cos(k.*d)+((111.0)./(2.*k))).*((sin(k.*d)));

Y=ceil(x);

subplot(121),

xlabel({'frequency','(in GHz)'})

ylabel({'RHS of the equation','([cos(k*d)+(111.11/2k)*sin(k*d)])'})

plot(k,Y);

Heyy now how do i find the cos inverse of the RHS of the above plot ??

how to find the cos inverse of (x) in the question..??
