If `tan^(-1)y=4tan^(-1)x(|x|

If tan^(-1) y = 4 tan^(-1) x (|x| lt tan (pi)/(8)) . Find y as an algebraic function of x, and, hence, prove that tan pi//8 is a root of the equation x^(4) - 6x^(2) + 1= 0

If tan^(-1)y=4tan^(-1)x then prove that x^4-6x^2+1=0 when 1/y = 0 and find the roots of x.

If tan^(-1)y=4tan^(-1)x , then 1//y is zero for

If tan^(-1)y=4tan^(-1)x, theny is infinite if

If tan^(-1)y=4tan^(-1)x then find the algebraic relation between x and y

If y is infinite and tan^(-1)y=4tan^(-1)x then

If tan^(-1)x+tan^(-1)y=(pi)/(4) , then cot^(-1)x+cot^(-1)y=

If tan^(-1)x+tan^(-1)y=(4 pi)/(5), find cot^(-1)x+cot^(-1)y
