If a sin x=b cosx=(2c tan x)/(1-tan^(2)x) , then prove that (a^(2)-b^(2))^(2)=4c^(2)(a^(2)+b^(2)).

If a sinx = b cos x = (2c tan x)/(1-tan^2 x) then show that (a^2-b^2)=4c^2(a^2+b^2) .

If tan x=(a)/(b) then show that (a sin x-b cos x)/(a sin x+b cos x)=(a^(2)-b^(2))/(a^(2)+b^(2))

If x = a sec A cos B, y = b sec A sin B and z = c tan A, show that : (x^(2))/ (a^(2)) + (y^(2))/ (b^(2)) - (z^(2))/(c^(2)) = 1

If (x)/(a)-(y)/(b) tan theta =1 and (x)/(a) tan theta +(y)/(b)=1 , then the value of (x^(2))/(a^(2))+(y^(2))/(b^(2)) is

If (x-a)cos theta+y sin theta=(x-a)cos phi+y sin phi=a and tan((theta)/(2))-tan((phi)/(2))=2b, then (a)y^(2)=2ax-(1-b^(2))x^(2)(b)tan((theta)/(2))=(1)/(x)(y+bx)(c)y^(2)=2bx-(1-a^(2))x^(2)(d)tan((phi)/(2))=(1)/(x)(y-bx)
