Simple computer graphics (OpenGL)

all of the following draws must be implemented using openGL 1- Draw the cardioid, rose, and spiral parametric curves. 2- draw the graph of the following functions and use windows to clip both them: y = x^3 + 2*x^2 + 3 y = 2*sin(x) + 0.5*cos(x) 3- Draw a smile emoji using dots only. 4- Draw a simple maze using lines only. 5- Draw any Islamic meander. 6- Find the bounding box for a polyline. Write a routine that computes the extent of the polyline stored in the array of points pt[i], for i = 0, 2, ..., n –1. 7- Find the matching viewport for a window with aspect ratio .75 when the screen window has width 640 and height 480. 8- Adjust the myReshape() routine above so that the viewport, rather than lying in the lower left corner of the display, is centered both vertically and horizontally in the screen window. At the end all of the 8 above MUST contain a picture and the source code.
