Simple but Stuck: How do I find the point of intersection of two lines in Vector Calculus? Given symmetric equations and deriving parametric equations.
Find the point of intersection of the lines L1: $\frac{x}{2} =\frac{y+1}{3} = \frac{z-1}{2}$ and L2: $\frac{x}{4} = \frac{y}{5} =\frac{z}{5}$
The parametric forms should be $x_1 = 2t$, $y_1 = -1+3t$, $z_1=1+2t$ and $x_2=4t$, $y_2=5t$, $z_2 = 5t$
The final solution is $(4, 5, 5)$. It almost looks like someone just grabbed the coefficients from the parametric form of the second line to make the point. Working backwards, how do I get this answer?
Sincerely,
In need of the process.
Thank you very much.
