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

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

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

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

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

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

f(x)=(cos x)/([2(x)/(pi)]+(1)/(2)) where x is not an integral multiple of pi and [.] denotes the greatest integer function,is (a)an odd function (b)an even function (c)neither odd nor even (d)none of these

If the phase difference between the two light waves interfering at point of the medium is equal to odd multiple of pi then tat point appears are

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