(1) 5 17 13. ufc tan-- a + tan-B + tanly = n, at Rates

If tan A+tan B+tan C=tan A . tan B . tan then

If A=tan 1, B = tan. 9/5 then

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

(a) tan A+tan B+tan C=tan A tan B tan C

Assertion A: If x+y+z=xyz then sum((2x)/(1-x^(2)))=pi((2x)/(1-x^(2))) Reason R: If tan A+tan B+tan C=tan A tan B tan C then A+B+C=n pi,n in N

In a triangle A B C, tan A+tan B+tan C=6 and tan A . tan B=2, then the values of tan A tan B and tan C are

Prove that tan13x = tan 4x + tan 9x + tan 4x tan 9x tan 13x

If tan(A+B) = m and tan (A - B) = n , find tan 2A and tan 2B in terms of m and n (mn != 1)
