" If "x=sec phi-tan phi&y=cosec phi+cot phi," then "

If x=sec phi-tan phi and y=cos ec phi+cot phi, then

If x=sec phi-tan phi and y=cos ec phi+cot phi then

If x=sec phi-tan phi and y=csc phi+cot phi then x=(y+1)/(y-1)( b) x=(y-1)/(y+1)y=(1+x)/(1-x)(d)xy+x-y+1=0

tan phi cos ec phi=sec phi

If x = sec phi - tan phi and y = cos ec phi + cot phi , then

The value of sqrt((cosec phi-cot phi)/(cosec phi +cot phi)) div (sin phi)/(1+cos phi) is equal to:

Given that (sec theta+tan theta)(sec phi+tan phi)(sec psi+tan psi)=(sec theta-tan theta)(sec phi-tan phi)(sec psi-tan psi) then Prove that value of each side +-1 is

If " "sec theta = 5/4, "cosec" phi = 13/12 " then find the value of " sec ( theta + phi).

The value of (sec phi(1-sin phi)(sin phi+cos phi) (sec phi+tan phi))/(sin phi(1+tan phi)+cos phi(1+ cot phi)) is equal to :

If 2sec2theta = tan phi + cot phi , then one of the values of theta + phi is:
