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

If cos A=4/5 , then the value of tanA is

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

If (1)/((tanA+cotA))=x , the the value of x is

If secA + tanA =a, then the value of cosA is यदि secA + tanA =a हो, तो cosA का मान क्या होगा?

If tanA = 4/3 , the value of sin A is:

If A and B are acute angles such that tanA=(1)/(3) , tanB=(1)/(2) and tan(A+B)=(tanA+tanB)/(1-tanAtanB) , Then find the value of A+B .

If ((cotAcotB-1))/((cotB+cotA))=x then the value of x is

In tanA=5/12 then the value of (cosA-sinA) cosec A is…….
