QFFE_207: "Illegal 'tan' argument: 'value'"
Tangent of the argument can not be calculated.
Cause
-
Tangent argument is an odd multiple of 90 for t = 30
tan(15*t) |
Illegal 'tan' argument: '450' |
-
Tangent argument becomes an odd multiple of 90 due to rounding errors
tan(90 - 1e-20) |
Illegal 'tan' argument: '90' |
Resolution
- Check that the value of tangent argument is never equal to an odd multiple
of 90.
- If the cause is in rounding errors, try to change the order of operations
to reduce their impact.
