Answer:
3π (540°) and 5π(900°)
Step-by-step explanation:
π radian = 180° degree
in the trigonimitrical cercle each point is taken by many values
so π position is also -π position
to move from π to -π you should move 360° (wich is 2π) backwards
π-2π = π
so -π = π +2π
you can get as much as you can of values similar to π using the formula :
π + 2*k*π where k is a relative number
π+ 2*1*π = 3π
π+2*2*π = 5π
3π is 540°
5π is 900°
