Answer:
1) (9, 75+360n)
2) (−9, 255+360n)
Step-by-step explanation:
(9, 75) is same as (9, 75 + 360)
so it would be (9, 435)
It can also be expressed as (-9, 75 + 180 degrees)
so (-9,255) degrees
In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)
Answer with explanation:
The Position of Point in two dimensional plane , P=(9,75°)
→The general rule of writing the point (r,Ф) in terms of polar coordinates is,
x=r cos Ф , y=r sin Ф
The angle between Intial side and terminal side is Acute.
Here, r=9 units
And , Ф=75°
→→Period of Cosine and Sine is 2π.
⇒⇒So,the coordinates of Point will be
x=9 *cos (2nπ+75°), And ,y=9 *sin (2nπ+75°), where n is any integer.
