सिद्ध कीजिए कि
`tan((pi)/(4)+x)+tan((pi)/(4)-x)=2sec2x`

Solve: tan(pi/4+x)+tan(pi/4-x)=2

Solve : tan(pi/4+x)+tan(pi/4-x)=4

tan x+(tan((pi)/(4))+tan x)/(1-tan((pi)/(4))tan x)=2

Prove that: tan(pi/4+A)+tan(pi/4-A) = 2sec2A

Prove that: tan(pi/4+A)+tan(pi/4-A) = 2sec2A

If 0 lt x lt (pi)/(2) , then find tan ((pi)/(4)+ (x)/(2) ) + tan ((pi)/(4) - (x)/(2) )

Provet that " tan " ((pi)/(4) +(x)/(2)) + " tan " ((pi)/(4)-(x)/(2)) = " 2 sec x"

tan^(-1)2x+tan^(-1)3x=(pi)/(4)

(sec2x-tan2x) equals a tan(x-(pi)/(4))b)tan((pi)/(4)-x)c cot(x-(pi)/(4))d tan^(2)(x+(pi)/(4))

If 0 lt x lt (pi)/(4), then sec 2x - tan 2x= ................ A) tan (x- (pi)/(4)) B) tan ((pi)/(4) -x) C) tan (x+(pi)/(4)) D) tan ^(2) (x+ (pi)/(4))
