I would appreciate a little help with a parametric equation please.
Example.
I want to eliminate t
so I change the sides
I now bring in the second equation
The above I have understood, but my next equation I am getting confused with.
I want to eliminate t
I am more than likely incorrect but am thinking along the lines of;
Therefore I can use x + 5 in place of t
In the next equation I think
combine the equations
I not sure any help appreciated
Example.
PHP:
x = t + 1
PHP:
y = 3t - 2
PHP:
x = t + 1
PHP:
t = x - 1
PHP:
y = 3t - 2 = 3(x - 1) - 2 = 3x - 5
PHP:
y = 3x - 5
PHP:
2x = 2t - 5
PHP:
2y = 14t + 9
I am more than likely incorrect but am thinking along the lines of;
PHP:
2x = 2t - 5
PHP:
x = t - 5
PHP:
t = x + 5
In the next equation I think
PHP:
2y = 14t + 9
PHP:
12y = t + 9
PHP:
3y = t
PHP:
t = 3y
PHP:
t = 3y (x + 5)
PHP:
t = 3xy + 15
