" 31.If "tan(x+y)=33" and "x=tan^(-1)3" then "y" will be "

tan(x+y)=(tan x+tan y)/(1-tan x tan y)

If x=2. y=3 , then tan^(-1)x+tan^(-1)y=

(tan(x+y)-tan x)/(1+tan(x+y)tan x)=tan y

(tan(x+y)-tan x)/(1+tan(x+y)tan x)=tan y

If tan(x+ y)tan(x-y)=1 , then the value of tan x is:

Show tht tan (x-y)=(tan x-tan y)/(1+tan x tan y)

If (tan^(-1)x)^(3)+(tan^(-1)y)^(3)=1-3tan^(-1)x.tan^(-1)y . Then which of the following may be true

If (tan^(-1)x)^(3)+(tan^(-1)y)^(3)=1-3tan^(-1)x.tan^(-1)y . Then which of the following may be true (a) (x+y)/(tan1)=-2 (b) (tan^(-1)x)/(1-tan^(-1)y)=2 (c) (tan^(-1)x)/(1-tan^(-1)y)=2 (d) (x+y)/(cot1)=1
