Find the direction cosines of the line x-2/2
WebA unit circle has a radius of one. Cosine is the x coordinate of where you intersected the unit circle, and sine is the y coordinate. Or if you had a vector of magnitude one, it would be cosine of that angle, would be the x component, for the, if we had a unit vector there in that direction. And then sine would be the y component. WebApr 18, 2024 · Given: l, m, n are the direction cosines of the line x - 1 = 2 (y + 3) = 1 - z. The given equation of lines can be re-written as x − 1 1 = y + 3 1 2 = z − 1 − 1. So, by comparing the equation x − 1 1 = y + 3 1 2 = z − 1 − 1 with x − x 1 a = y − y 1 b = z − z 1 c we get. ⇒ a = 1, b = 1/2 and c = - 1. As we know, if a, b, c ...
