Jaymar`s Theory: ;P
ReplyDeleteIn finding the coterminal angles and their coordinates:
-If a radian measure is an odd whole number, then it is a multiple of π, and therefore terminates at the same angle which is at 180 degrees.
-If a radian measure is an even whole number, then it is a multiple of 2π and therefore terminates at the same angle which is at 360 degrees.
therefore,
in odd numbers: cosθ = -1 & sinθ = 0
and
in even numbers: cosθ = 1 & sinθ = 0
