No, I’m talking about your inverse cosine result that you called on.ur trolling.
inverse sin + inverse cos = pi/2 is like by definition basically.
is this assuming?
if x+y =zNo, I’m talking about your inverse cosine result that you called on.
If it took you three lines to explain that it isn't so obvious?if x+y =z
and there's an equation
x+3a = z
obviously 3a = y no?
.....If it took you three lines to explain that it isn't so obvious?
i love how we're considering these parts.If it took you three lines to explain that it isn't so obvious?
On the subject of unobvious-ity. i doubt i would see that hidden quadratic you did in suitable minutes in an exam.If it took you three lines to explain that it isn't so obvious?
Actually, the part where you hadOn the subject of unobvious-ity. i doubt i would see that hidden quadratic you did in suitable minutes in an exam.
we all know mathematicians use 'trivial' to skip working out because they're a tad lazy hahaha.I think the use of the word “obviously” was misleading because normally that is used to call on a result, not used in place of a “hence” or “therefore”.
Either way, the part where you have an equation in terms of u is not trivial and is missing some working.
???????Actually, the part where you had
lends itself to an obvious quadratic by cosine double angles.
Yeah, once you become an actual mathematician and writing academic papers. That will never fly in an exam at school or uni though lolwe all know mathematicians use 'trivial' to skip working out because they're a tad lazy hahaha.
oh ye pretty nice quadratic. working out up to that quadratic looks nicer than @Qeru's lol.???????
but it flies in textbooks lol.Yeah, once you become an actual mathematician and writing academic papers. That will never fly in an exam at school or uni lol
dont u learn that in junior years?I think if you explained why and added some explanation between steps your proof would have made more sense.
