i am given parametric equations of 2 lines L1 and L2 and i am asked to find the vector, parametric and symmetric equation of a line that intersects these 2 lines at 90 degrees so a line that is perpendicular to those 2 lines. how do i go about this? at first i tried converting the parametric equation to a vector equation to get the value of vector a cause p vector = a vector + t(b vector) and then cross multiplying the two a vectors. but then i realized that the a vectors dont have the same direction and that the line and the a vector are totally different things so ... how do i go about this?(adsbygoogle = window.adsbygoogle || []).push({});
