If angles A and B satisfy `(1+tanA)(1+tanB)=2`, then the value of A +B is

If (1+tanA)(1+tanB)=2 , then tan(A+B)=

If cos(A - B) = (3)/(5) and tanA tanB = 2, then the value of cosA cosB is _____

If an angle theta is divided into two parts A and B such that A-B=x and tanA :tanB=k :1 , then the value of sinx is

In a triangle, tanA + tanB + tanC = 6 and tanA tanB = 2 , then the values of tanA, tanB, tanC are :

Let A , B , C be the three angles such that A+B+C=pi . If tanA.tanB=2, then find the value of (cosAcosB)/(cosC)

Let A , B , C be the three angles such that A+B+C=pi . If tanA.tanB=2, then find the value of (cosAcosB)/(cosC)

Let A ,B,C, be the three angles such that A+B+C =pi .If tanA*tanB=2 .Then find the value of (cosAcosB)/(cosC) .

If A+B=315^@ then (1-tanA)(1-tanB)=

If A+B=pi/4 show that (1+tanA)(1+tanB)=2

If A+B=45^@ then (1+tanA)(1+tanB)=
