Question

Please use matlab

cars. Answer: Function file; Command Window: 5.4 Write a user-defined function that plots a circle given the coordinates of the center and the radius. For the function name and arguments use circleplot(x,y,R). The input arguments are the and y coordinates of the center and the radius. Use linspace to generte the angle from 0 to π with 100 points. (Hint: the circle equation: x+Rcos and yy-yRsin 0.) This function has no output arguments. Plot the circle using the green color and set axis equal. Also label x and y-axis. Show the function file and the resulting figures. Use the function to plot the following circles: (a) x-35, y 2.0, R 8.5 Answer: Function circleplot.m: (b) x 4.0, y 1.5, R- 10 Command Window:

Answer 1

(a)
function a=circleplot(xc,yc,r)

th=0:0.01:2*pi

x=xc+r*cos(th);

y=yc+r*sin(th);

plot(x,y);

end

(b)
function a=circleplot(xc,yc,r)

th=0:0.01:2*pi

x=xc+r*cos(th);

y=yc+r*sin(th);

plot(x,y);

end
