Last minute proofs etc (1 Viewer)

[untouchablecuz]

any well known proofs etc we should know?

 

[kaz1]

PS + PS' =2a for hyperbola and ellipse, the multiplicity of roots with the derivative, the integration with f(x) and f(a-x). There's probably more.

De Moivres theorem.You can do it for n≥0, and then replace n with -n in the expression, and prove it for n ≤ 0.

AM ≥ GM lol.

chord of contact for E and H polynomial stuff dunno if these are proofs but all those reduction formulas with sin, cos, tan, sec, cot, cosec anddddddd resovling forces for bankedmotion n conical cuz theyre usualyl all the same n saves you time for exam

how to prove the polynomial theorems, multiplicity and the complex conjugate roots.
foci, directrix, asymptotes, and eccentricity for hyperbola's and ellipses
resolving forces in mechanics
integration, the special properties
graphing, how to draw if the absolute values, square roots and what not
Volume formula's, the slice method and shells method
circle geo proofs

not all are proofs, but some handy dandy things to remember.

PM + PM' =2a for hyperbola and ellipse, the multiplicity of roots with the derivative, the integration with f(x) and f(a-x). There's probably more.

i still can't do the PM +PM`= 2a lol how do you do it exactly?

 

[Dimplez]

the properties for conjugate complex numbers? By the way, does anyone know the E3 cutoff in ext 2?

i still can't do the PM +PM`= 2a lol how do you do it exactly?

lol meant to write PS + PS'=2a, you use the locus definition of PS=ePM ,Same in both hyperbola and ellipses PS+PS'=e(PM+PM') =e(2a/e) =2a

How do you dervice the complex conjugates proof?

[untouchablecuz]

i got one: know how to prove that a root of a polynomial is a divisor of the constant term and term of the highest power

 

[Aerath]

untouchablecuz - how did you type it out like that? =\

 

[untouchablecuz]

er, using latex

 

[study-freak]

Need to be able to prove this although it's one of the easiest proofs

 

[Aerath]

er, using latex

But quick reply doesn't work....my Latex thing goes straight into quick reply.

Works on firefox, try using a different browser ^^

hey annabackwards
dont forget 1 + 1 = window
could cost you your e4

Yes, sir! Ahaha trolls who know how to insert line breaks, how far we've come ^^
