यदि ` tan A =( 5)/(6)` और ` tan B =(1)/(11) ` तो सिद्ध कीजिए की
` " " A+ B=45^(@)`

tan A=(5)/(6) andtanB =(1)/(11), prove that A+B=(pi)/(4)

If tan A=5/6, tan B=1/11," show that A+B=45"^(@) .

If tan theta=(5)/(6) and tan phi=(1)/(11) , then theta+phi =______

tan(A+B)=(tan A+tan B)/(1-tan A tan B)

If (tan A)/(2)=(5)/(6),(tan B)/(2)=(20)/(37). Then sides are

If sin A = (3)/(5) and cos B = (12)/(13) . Then the value of (tan A - tan B)/(1 + tan A tan B) is equal to

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

If tan ^(-1) a^(3)+tan ^(-1) a=tan ^(-1) b, then b=

If A + B = 45^(@) , show that (1 + tan A)( 1 + tan B) = 2
