Equation:
sin(x) + sin(p - x) equals:
Answers:
0
1
2sin(x)
sin(x) + cos(x)
cos2(x)
Sine chick asked me this and I took the god damned GERD.... Sin and shit was RARELY used in Algebra2.... in ohio.... Sc is stupider obviously.. I damned there passed it with my best subject beoing my worst.....
But the question is no answer unless you know p or X.... or can remake the equation and an answer...
Anyone know this one?

I absolutely hate math. Hate it. With a passion.

Math > you.
Let p = 10
Then x = 5
2sin(x) would be the answer.
Mathematics is art at its finest.

No. Philosophy is art at its finest. Math is mechanical and unchanging. No surprises. Nothing new.
Math is no more an art form than crossword puzzles are.

Faaairly sure sin(x) + cos(x).
Algebra - Retane - 09-25-2006
Dbl post lol
Algebra - Retane - 09-25-2006
I honestly dunno... I felt it should become an equation as an answer but I dunno what sin or cos mean on a calculator....
X an P are not defined...
Algebra - Hellfighter 17 - 09-25-2006
x and p don't necassarily need to be defined. I don't take trigonometry until next semester, so I cannot be sure, but it seems as though you must assume that p is static and only x can vary.

It's 0
sin(x) + sin(p - x) = sin(x) + sin(p)cos(x) - cos(p)sin(x) if you than simplify the equation it ends up being cos(p) - cos(p) which equals 0.

I should have said 1, since it becomes x + cos(px) - cos(px)
Algebra - Hellfighter 17 - 09-25-2006
Only if x = 1, right?
Algebra - Jewtastic - 09-25-2006
You assume x=1
Algebra - Drake - 09-25-2006
No, only as long as x > 0, it will work out. And since it is trig it should work out, since 0 wouldn't show up on a graph I believe.
Algebra - Hellfighter 17 - 09-25-2006
I forget the technical terms, but I believe it could just turn out as looking like a straight line. Also, you can have negative angles.
Algebra - Drake - 09-25-2006
Trig is stupid anyway, it's been like 6 years. >.>

Take B30 again, then. That would mean you are, like, 23 or 24. =O

Yup, I took b30 and c30 in one semester ~_^ and passed both- got like 87 on the final. Buwauaha. It's only cause I failed b30 in grade 11; damn pokemon blue!
Algebra - Hellfighter 17 - 09-25-2006
Oh, yea, C30 is trigonometry; I'm taking B30 this semester. Yea, well, I took Math10 and Math20 in one semester! Oh, brun!
