I'm sorry, but if you are unable to understand the basics of calculus and discrete math, then you should not be in a Computer Science program (with emphasis on the "science" part). CS isn't just programming - it's the theory of how computers work and math is an integral part of that. Just because you don't use it every day in the job itself doesn't mean that the information is useless.
It's sort of a PITA. Click on the name of the person who sent you the LUT in iMessage and scroll down to "Documents". Tap on the LUT file. Use the Share button in the lower left corner and then, where it lists the apps, tap "More". You'll see Kino listed. If you tap it, it will automatically import it.
Again, PITA, but given the iOS infrastructure, I'm surprised it works at all.
