omg hi i remember you!! :)
ah, well that's another thing... academic dishonesty is NEVER okay :0 but OP if you are actually willing to learn how to do this, maybe make a problem similar to it? idk...so it doesn't look like you're like trying to cheat or anything. And, maybe you weren't intending to do that, but yeah...
idk, ngl i was pretty confused too when i first heard of that notation but the teacher said like that's how it works in trig or something and that's how we will be doing it
i agree with melody, since there are multiple formulas for solving quadratics, and it depends on what the context asks you to do!
it's all good!! :) don't worry about it i know what you meant
wait wait wait,,, i agree with everything you just said except for one thing... shouldn't 90 degree rotations do this to a point?? \((x,y)\rightarrow(-y,x)\) but thank you for your help :) your answer was extremely clear to understand.
thank you guys so much!!
great explanation CPhill!!
I know that unfortunately, there are some users that might want to cheat, but we can't just assume that every person who asks a specific question is a cheater... maybe OP is actually trying to learn the material.... :')
Amazing explanation asinus!!
