plotting a function with input and output

here is my code. hw prompt below. what do you recommend i do?

t=0:0.01*pi:20*pi;

function [x,y]=bird(t)

x(t)=sin(t)*(e.^cos(t) -2*cos(4*t)-sin.^5(t/12))

y(t)=cos(t)*(e.^cos(t) -2*cos(4*t)-sin.^5(t/12))

plot(x,y)

You need to change * to .* and change e to exp(), and you need to move the 5 exponent:

t=0:0.01*pi:20*pi; % Create t
[x, y] = bird(t); % Call the function.

function [x,y] = bird(t)
x = sin(t) .* (exp(cos(t)) - 2*cos(4*t)-sin(t/12).^5)
y = cos(t) .* (exp(cos(t)) - 2*cos(4*t)-sin(t/12).^5)
plot(x,y)
end

Main script

t=0:.01*pi:20*pi;
[x,y]=bird(t);
plot(x,y);

function

function [x,y]=bird(t)
  x=sin(t).*(exp(cos(t)) -2*cos(4*t)-sin(t/12).^5);
  y=cos(t).*(exp(cos(t)) -2*cos(4*t)-sin(t/12).^5);
end
