 young nabhab. Did you take real analysis for math minor taking that that this semester? I forget what it was called, it was we looked at systems right and we looked at trying to predict like here here's one example of an applied mathematics course problem that we needed to solve like this this is one of the questions we had in class right and this was actually not the hardest this wasn't then this was the prerequisite for the hardest applied math course I took so the prerequisite was easier the the system that I'm gonna tell you the analysis that we did for the system was the easier course that we took the next level course insane I studied 10 days straight 10 to 12 hours a day the final took five and a half hours or something like this only got to 75 it's a long story but here's a problem with an applied mathematics that we had to solve in for this class this was like a sento assignment right we had a here's the scenario there's a river okay there is two streams coming out of a river with a certain flow and there's three streams coming into the river with a certain flow the there's fish in the into the lake with a certain flow so there's a lake two streams going out three streams coming in okay there's fish in the lake now the fish can handle acidity level of a certain level certain degree I forget what it was or toxicity level right the three streams coming in have a certain toxicity each each stream that's pumping into the lake right there's factories up upstream right so the question was this how much toxicity can you allow these factories to put into the rivers that are coming into this lake so the fish can still live so we're playing with a threshold right and we had to do analysis on this it was a cool problem I thinking back at it now it's just like Matt why we even flirting with disaster like that but it was a math it was a math problem it was cool problem okay
