Trace the curve 𝑦2 = (𝑥 − 1)(2𝑥 + 3)(3𝑥 − 1).
The distance from the point P(1,3,2) to the line through (1,0,0), and (1,2,0) is given by ?
Suppose u = (u1; u2; u3) :
Prove that
u x u = u21+ u22+ u23
whats the relationship between (2,1,2) and the line L represented by parametric equations x=1+2t,y=2+t,z=3-2t where t is an element of R
