" vi."y=(1-cos x)/(1+cos x)

If y= (cos x)^((cos x)^((cos x)……oo)) , then show that (dy)/(dx)= (y^(2) tan x)/(y.log cos x-1)

cos ^(-1) ""((cos x + cos y)/(1+cos x cos y))= 2 tan ^(-1) (tan ""(x)/(2) tan ""(y)/(2))

If y=| a^(2) a 1 (cos x)/(cos n)(x+1) cos n(x+1)+c (dy)/(dx)=

If y=| a^(2) a 1 (cos x)/(cos n)(x+1) cos n(x-1)+c (dy)/(dx)=

If cos x+cos y=1 and cos x cos y=(1)/(4) then the G.S are

If y=(a^cos^((-1)x))/(1+a^cos^((-1)x)) and z=a^cos^((-1)x) , then (dy)/(dz) is equal to........

If y=(a^(cos^-1x))/(1+a^(cos^-1x))andz=a^(cos^-1x),then (dy)/(dx) =

If y=(a^(cos^-1x))/(1+a^(cos^-1x)) and z= a^(cos^-1x) , then dy/dz=

Draw the graph of following function y = cos ^ (- 1) (cos x) y = sin ^ (- 1) (sin x) y = cos (cos ^ (- 1) x) y = sin (sin ^ (- 1) x)
