" 8."cos B=(12)/(13)

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

If sin A=(3)/(5),0

If cos A=(12)/(13) then find sin A and tan A

cos. (pi)/(13) + cos. (5pi)/(13) + cos. (8pi)/(13) + cos. (12pi)/(13)=

If P(A) = (5)/(13) , P (B) = (9)/(13) and P (A cup B) = (12)/(13) then find P (A|B).

If sin B = (12)/(13) , then find cot B.

sec A=cosec B=(13)/(12) then (A+B)=

Prove that "cos" (3pi)/13 + "cos" (5pi)/13 - 2 "cos" (9pi)/13 "cos" (12pi)/13 = 0

Prove that : cos^(-1).(3)/(5)+ cos^(-1).(12)/(13) = sin^(-1)((12)/(5))

If sin A= 4/5 and cos B =- 12/13, where A and B lie in first and third quadrant respectively, then cos (A+B)=
