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

Given that tan(A+B)=(tan A+tan B)/(1-tan A tan B) find the values of tan75^(@) and tan90^(@) by taking suitable values

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

if A+B=135^(@) then (tan A.tan B)/((1+tan A)*(1+tan B))=

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

Prove that (tan (AB) + tan B) / (1-tan (AB) tan B) = tan A

For all values of A and Btan(A+B)=(tan A+tan B)/(1-tan A tan B) and tan(A-B)=(tan A-tan B)/(1+tan A tan B)

In a triangle ABC , right angled at A ,the altitude through A and internal bisector of /_A have lengths 3 and 4 respectively. Find the length of median through A. Given that tan(A+B)=(tan A+tan B)/(1-tan A tan B),tan(A-B)=(tan A-tan B)/(1+tan A tan B)
