B: -tan(25)
cot 115 deg = - tan25 deg
Tan 42 degrees = 0.9004
outside temps above 100 degrees
Yes. The ability to tan has nothing to do with the temperature. But how strong the suns rays are. You can get a tan while its overcast for instance. (ie burnt face while snow skiing). If you can feel your skin warming up from the UV rays you will get a tan.
75 degrees Celsius
tan(11o) = 0.19438 =======
