`A/2` is not an odd multiple of `(pi)/(2)` ,then `tan(A/2)=`

If (A)/(2) and A are not an odd multiple of (pi)/(2) .then tan A=

If (A)/(2) and A are not an odd multiple of (pi)/(2) then tan A= (2tan A)/(1-tan^(2)A) (2tan A)/(1+tan^(2)A) (2tan (A/2))/(1-tan^(2)(A/2))

For any real number A ,which is not an odd multiple of (pi)/(2) , sin2A=

If A+B=45^(0) and none of A and B is an odd multiple of (pi)/(2) ,prove that (1+tan A)(1+tan B)=2 and hence deduce that tan22(1)/(2)=sqrt(2)-1

If {:E(theta)=[(cos^2 theta,costhetasintheta),(costhetasintheta,sin^2theta)]:},and thetaand phi differ by an odd multiple of pi//2," then "E(theta)E(phi) is a

If A+B+C=(pi)/(2) then tan2A+tan2B+tan2C=

If for complex numbers z_1 and z_2, |z_1+z_2|=|z_1|=|z_2| then argz_1-argz_2= (A) an even multiple of pi (B) an odd multiple of pi (C) an odd multiple of pi/2 (D) none of these
