The normal form of the line whose perpendicular from the origin has length 2 and makes an angle of 30^circ with the x-axis is:

  1. xcos 30^circ + ysin 30^circ = 2
  2. xcos 30^circ + ysin 30^circ = 4
  3. xsin 30^circ + ycos 30^circ = 2
  4. xcos 30^circ - ysin 30^circ = 2
Answer

A) xcos 30^circ + ysin 30^circ = 2

Normal form: xcosalpha + ysinalpha = p. Here this is x ( 32 ) + y ( 12 ) = 2. SLO M-09-B-08 · Understanding
