For a square or rectangle, if you have x1, x2, y1, and y2, you can make it with plot by making coordinates of the box and calling plot. xBox = [x1 x2 x2 x1 x1]; yBox = [y1 y1 y2 y2 y1]; plot (xBox, yBox, 'r-', 'LineWidth', 2); Of course that can ge generalized to any polygon, just list all the vertices.

Find the missing coordinate of P, using the fact that P lies on the unit circle in the given quadrant. Coordinates Quadrant P (-4/5) III --------------- If it's the y coordinate: y = -3/5 (negative in Q3) ============= It could be x or y.
Now the word 'secant' means 'to cut', so a secant line is any line that 'cuts through' a circle at two points.2 The line containing the terminal side of is a secant line since it intersects the Unit Circle in Quadrants I and III. With the point P lying on the Unit Circle, the length of the hypotenuse of OPAis 1.

Given the forces F1 = 6.12 N, F2 = 4.32 N, F3 = 1.84 N and their angles α = 16° , β = 22° , γ = 36°, calculate the force resultant R and its angles αR , βR , γR with the x, y and z axis. The forces are diagonals on each side of a rectangular parallelepiped. Step 1. Calculate the force projections on each axis. Step 2.

The distance around a circle on the other hand is called the circumference (c). A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).
