How to find the direction vectors …?
I have this exercise in mathematics and I do not know how to find the direction vectors the following two equations: 1. R = 2i-j +3 K + S (3i 4 k) 2. r = 2d + kt (i + j-2k) The book gives me the answer. But they said .. If someone could help me, would be great!
1, the direction vector is s (3i + 4k )…………. is the position vector 2i – j + 3k or you can write the vectors so that s <3, 0, 4> and <2, -1, 3> 2, the direction vector is t (i + j – 2k) and the vector position 2j – k. see link
