INVERSE TRIG FUNCTIONS >> There are actually 2 angles that are potential answers even though the calculator only gives 1 answer!
Cos-1 (X Projection)
Cos-1 (X Projection)
Angle = calculator value
or
Angle = 360 - calculator value
Sin -1 (Y Projection)
Sin -1 (Y Projection)
Angle = calculator value
or
Angle = 180 - calculator value
Tan -1 (Slope = Y/X)
Tan -1 (Slope = Y/X)
Angle = calculator value
or
Angle = 180 + calculator value
NOTE: For a 0-360 Global Direction Answer ... if angular value is negative, add 360.
Adding 360 will spin the direction a full circle ... thus adding 360 does not change the angular direction!
