Coterminal angles with -315 degrees are 45 degrees, 405 degrees, -675 degrees, -1035 degrees, 45π/180 radians, 405π/180 radians, -675π/180 radians, -1035π/180 radians.
Solución
To find angles that are coterminal with -315 degrees, we can add or subtract multiples of 360 degrees.
Adding 360 degrees to -315 degrees gives us -315 + 360 = 45 degrees.
Adding another 360 degrees gives us 45 + 360 = 405 degrees.
Subtracting 360 degrees from -315 degrees gives us -315 - 360 = -675 degrees.
Subtracting another 360 degrees gives us -675 - 360 = -1035 degrees.
Therefore, two positive angles that are coterminal with -315 degrees are 45 degrees and 405 degrees, and two negative angles that are coterminal with -315 degrees are -675 degrees and -1035 degrees.
In radians, we can use the same process.
Adding 2π radians to -315π/180 radians gives us -315π/180 + 2π = -315π/180 + 360π/180 = 45π/180 radians.
Adding another 2π radians gives us 45π/180 + 2π = 45π/180 + 360π/180 = 405π/180 radians.
Subtracting 2π radians from -315π/180 radians gives us -315π/180 - 2π = -315π/180 - 360π/180 = -675π/180 radians.
Subtracting another 2π radians gives us -675π/180 - 2π = -675π/180 - 360π/180 = -1035π/180 radians.
Therefore, two positive angles that are coterminal with -315π/180 radians are 45π/180 radians and 405π/180 radians, and two negative angles that are coterminal with -315π/180 radians are -675π/180 radians and -1035π/180 radians.
So the answer is: 45 degrees, 405 degrees, -675 degrees, -1035 degrees, 45π/180 radians, 405π/180 radians, -675π/180 radians, -1035π/180 radians.
