The parametric equation: x = t / (1-2T ^ 2), y = (1-2T ^ 2) / (1 + 2T ^ 2) is transformed into a general equation

The parametric equation: x = t / (1-2T ^ 2), y = (1-2T ^ 2) / (1 + 2T ^ 2) is transformed into a general equation


It can be obtained from y = (1-2T & # 178;) / (1 + 2T & # 178;)
t²=(1-y)/(2+2y)
be
t=……
You can get it by substituting X



Let the parameter equation of the line be x = 5 + 3T, y = 10-4t (t is the parameter)


X = 5 + 3T times 4 to get 4x = 20 + 12t
Y = 10-4t multiply by 3 to get 3Y = 30-12t
The sum of the two formulas leads to
4x+3y=50
