1.If `sin^(-1) x+cos^(-1) x=p`, then find `2tan(p /(3)) /(1-tan^(2) (p /(3)) `A) 1.96, B) 1.41, C) 1.73, D) 1.21

If tan^(-1)x,tan^(-1)y,tan^(-1)z are in A.P the (2y)/(1-y^(2))=

int((p+q tan^(-1)x))/(1+x^(2))dx

If x=sin(2tan^(-1)3)and y=sin((1)/(2)tan^(-1)(4/3)) , then

tan ^ (- 1) ((cos x-sin x) / (cos x + sin x)) = tan ^ (- 1) ((1-tan x) / (1 + tan x))

If (sin A + cos A) / ( sin A - cos A) = 5/4 , the value of (tan 2 A + 1) / (tan 2 A - 1) = ? A. 41/40 B. 12/13 C. 40 / 41 D. 3/5

If p(x) =x^(2)-4x+3, then evaluate p(2) -p(-1)+p((1)/(2)) .

(1)/(2)cos^(-1)((5cos x+3)/(5+3cos x))=tan^(-1)((1)/(2)(tan x)/(2))

(x^(2)+x+1)p(x-1)=(x^(2)-x+1)p(x) If p(1)=3 then find int_(-2)^(1)(dx)/(p(x)+x)

sin(cot^(-1)(tan(cos^(-1)x))) is equal to a x b sqrt(1-x^(2)) c) (1)/(x) d) none of these
