With slope in degrees and grade in percent, 100*tan(slope) = grade% slope = arctan(grade%/100) so 110% is about 47.7 degrees, and tan(90 degrees) is infinite

With slope in degrees and grade in percent,
100*tan(slope) = grade%
slope = arctan(grade%/100)
so 110% is about 47.7 degrees, and tan(90 degrees) is infinitely large.
