If 2x = sec theta and 2/x = tan theta , then 2(x^2 - (1)/(x^2)) =

if sec A=2x and tan A=(2)/(x), find the value of 2(x^(2)-(1)/(x^(2)))

If 2x= sec A " and "2/x = tan A , then the value of 2(x^2 - 1/x^2) will be

If sec A+tan A=x then sec A=(x^(2)-1)/(x)

sec 2x - tan 2x=

If tan(x/2)=cosec x-sin x" then (1+sec^(2)(x)/(2))^(2)=

(tan 2x)/(1+ sec 2x) = tan x

tan theta+sec theta=x show that 2tan theta=x-(1)/(x),2sec theta=x+(1)/(x) hence prove that sin theta=(x^(2)-1)/(x^(2)+1)

log (sec 2x +tan 2 x)

if sec A=x+(1)/(4x) then prove that sec A+tan A=2x,(1)/(2x)
