If It's known the equation of the hyperbolas, that is:
we can graph the hyperbolas in this way:
-
find the center
#C(x_c,y_c)# ; -
make a rectangle with the center in
#C# and with sides#2a# and#2b# ; -
draw the lines that pass from the opposite vertices of the rectangle (the asymptotes);
-
if the sign of
#1# is#+# , than the two branches are left and right of the rectangule and the vertices are in the middle of the vertical sides, if the sign of#1# is#-# , than the two branches are up and down of the rectangule and the vertices are in the middle of the horizontal sides.
