but how

the number of real roots in (6-x)⁴ + (8-x)⁴ = 16 are..........

HOW CAN WE WRITE

sinAsinB/cosAcosB = 1/tanC

AS

(sinASinB - cosAcosB)/(sinAsinB + cosAcosB) = (1 - tanC)/(1 + tanc)

a system shown in fig, blocks 2&3 kg are at rest.coefficient of friction getween 2 kg & incline is

(a)2/?3 (b)1/2

(c)1/3 (d)can't be calculated

ANSWER IS (d)can't be calculated WHY???????

--------------------------------------------------------------

my answer was

after resolving & equating x & y components along the plane,

we have f + T = mg sin30

FF m = 2/?3 i.e.(a)

Hi,

can u plz give me the download link for

Fundamentals of Physics , by Robert Resnick, Jearl Walker, David Halliday

well thanks,
that worked

sorry,it was a computer fault

If x₁,x₂,x_3,........x_n are the roots of the equation

xⁿ + p₁x^n-1 + p₂x^n-2 + ....+ p_n-1x + p_n = 0 ,(p₁, p₂, p₃,...p_n real) , prove that

(1 + x₁²) (1 + x₁²) (1 + x₁²)..... (1 + x₁²) =
(1 - p₂ + p₄ - p₆ +....)²+ (p₁- p₃+ p₅ - p₇+.....)^2.

If x₁,x₂,x_3,........x_n are the roots of the equation

xⁿ + p₁x^n?1 + p₂x^n?2 + ....+ p_n?1x + p_n = 0 ,(p₁, p₂, p₃,?p_n real) , prove that

(1 + x₁²) (1 + x₁²) (1 + x₁²)?.. (1 + x₁²) =
(1 ? p₂ + p₄ ? p₆ +....)²+ (p₁? p₃+ p₅ ? p₇+?..)^2.

If x₁, x₂, x₃?? x_n are the roots of the equation

xⁿ + p₁x^n?1 + p₂x^n?2 + ??..+ p_n?1x + p_n = 0 ,(p₁, p₂, p₃,?? p_n real) , prove that

(1 + x₁²) (1 + x₁²) (1 + x₁²)?. (1 + x₁²) = (1 ? p₂ + p₂ ? p₂ +?.)²+ (p₁? p₃+ p₅? p₇+?)²
