hey. what program do you guys use for math? like an algebraic program that does maybe trig functions or even calculus?

pic related, its a shitty example but i want something more open source/free.

Hahahahaha. Constantly he tries to partake in discussions about physics and biology and constantly gets basic facts wrong, making a fool of himself incessantly and then REFUSING to admit and come to terms with the fact he was wrong.
In addition, the moron tries to help with high-school homework threads, encouraging the plague of 13 year olds to return for more. If that is not enough he confuses people genuinely interested in a subject by supplying wrong and blatantly ignorant information.

Not going to waste my time trawling through green-oval, but recent examples include you being ignorant of basic principles of relativity despite claiming to understand it well, not understanding male sexuality at all and claiming otherwise, etc.

Yes other anons happen to be wrong but when they are and their errors are pointed out to them, they do not post retarded reaction images and try and make out that they are right or that they were trolling. This is why everyone on this board hates you

P.S. anyone claiming they don't hate you is trolling the fuck out of you to the rest of the board's delight. Pretty funny watching you believe people actually like you on this board hahah

thats such an overexaggeration, i was slightly wrong about one small fact, that doesn't mean i now magically know absolutely nothing about male sexuality.

and i dont make out i was right, or i was trolling. i accept when i am wrong, it sometimes happens, but so far you have only provided 2 examples, one of which hasnt even been fully explained and one of which is a massive over-exaggeration.

special relativity is contained in the set of things that are called science and math

Doesn't mean that it is a prerequisite for each subject in the entire set of things that are math and science.


I guess i am playing devil advocate with EK, but I refuse to feel negatively toward someone for any reason other than my own experience. My opinion of a particular tripfag is not interesting enough (even to me) to discuss any further.


On an semi-related note, I'm curious about the .51c objects moving away from each other. I'd instinctively thing that they would be moving away from each other at 1.02c. How does it work?

With regards to EK, I wouldn't trust anything related to physics, chemistry, or math coming from a zoology major.

My general experience is that they know close to nothing abou the subject because they typically take introductory classes in those subjects.

For whatever reason though she seems to get even biology questions wrong frequently.
