Question

Obtain the equation of the straight line in the normal form, for α (the angle between the perpendicular to the line from the origin and the X – axis) for each of the following , on the same graph :

(i) α < 90°
(ii) 90° < α < 180°
(iii) 180° < α < 270°
(iv) 270° < α < 360°

*PLEASE EXPLAIN IN DETAIL AND DRAW THE DIAGRAM, ON THE GRAPH, MENTIONED HERE*

Answer 1

Answer:

step by step explanation:

We know that the equation of the straight line upon which the length of the perpendicular from the origin is p and this perpendicular makes an angle α with x-axis is x cos α + y sin α = p. ⇒ x + y = 7√2, which is the required equation.
