Find the equation of the line for which

p = 3 and ∝ = 2250

Given: p = 3 and ∝ = 2250

Here p is the perpendicular that makes an angle ∝ with positive direction of x-axis , hence the equation of the straight line is given by:

Formula used:

x cos ∝ + y sin ∝ =p

x cos 2250 + y sin 2250 =3

i.e; cos 2250 = cos ((6360) +90) = cos((62 )+ 90)= cos 90

similarly, sin 2250 = sin ((660) + 90) = sin((62 ) +90)= sin 90

hence, x cos 90 + y sin 90 =3

x (0)+y1=3

Hence The required equation of the line is y=3.
