Stuck on a Maths
While i was Programming My Brother Got stuck into a problem of Mathematics
I also can't solve it
would anybody please solve it
----------------------------------------
Here is the problem
----------------------------------------
If x=cy+bz, y=az+cx, z=bx+ay
Then show that
x²/(1-a²) + y²/(1-b²) = z² / (1-c²)
----------------------------------------
Would anybody Please solve It
Thanks

No no Its the Question Nothing Is Missing
Nothing Else Is Given
I am reapiting It

Code: Select all
If x=cy+bz, y=az+cx, z=bx+ay
Then show that
x²/(1-a²) + y²/(1-b²) = z² / (1-c²)- RobertGonzalez

You need to substitute to show equality.
Would yield:
Now extrapolate the squares, handle the algebra and check to make sure that both side are equal.
Code: Select all
If x=cy+bz, y=az+cx, z=bx+ay
Then show that
x²/(1-a²) + y²/(1-b²) = z² / (1-c²)Code: Select all
(vy+bz)²/(1-a²) + (ax+cx)²/(1-b²) = (bx+ay)² / (1-c²)- neel_basu

Sorry
Just Now I Looked At the erratta of his book

I dont think algebra is so bad to hateshwanky wrote:Algebra is the only trick :-/. I had a professor who would give this crazy proofs on tests worth 15-20% of our class grade. He only taught us algebra and how it applies to trig and calculs... I hate algebra
I Liked Algebra (Speciely Sequence And series) And I also liked Calcullas (Specially Indefinite Integral very much) and Electro magnetism in physics very much
When I was in 10+2.
But I don't like lobourous maths I like the tricky problems.
