Add 2π (one full turn).
-π/2 + 2π = -π/2 + 4π/2 = 3π/2.
So a positive coterminal angle is 3π/2 radians ( = 270° ).
More generally, coterminal angles are -π/2 + 2kπ for any integer k.
-π/2 + 2π = -π/2 + 4π/2 = 3π/2.
So a positive coterminal angle is 3π/2 radians ( = 270° ).
More generally, coterminal angles are -π/2 + 2kπ for any integer k.
