Question

If ( tan(A-B)/tan A )+ Sin**2 C/sin**2 A), then
prove that tanA tanB = tan**2 c

Answer 1

can you retype the problem? not that clear here, sorry. :(

Answer 2

yeah sure

Answer 3

yeah sure
\[(\tan(A+B)/\tan A) + \sin ^{2}C/\sin ^{2}A \]

then prove that
\[(\tan A )(\tan B)=\tan ^{2}C\]

Answer 4

working on it.

Answer 5

thanx

Answer 6

i think you are missing an equal sign in the first expression...
if "equation" is true, then prove this equation holds

Answer 7

i think so, can you clarify that part?

Answer 8

@jainilk.... pls clarify....

Answer 9

yeah sorry
RHS in first equation is 1

Answer 10

tan(A-B)/tan A )+ Sin**2 C/sin**2 A
\[\huge \frac{tan(A-B)}{tan A }+\frac{sin^2C}{sin^2A}=1 \]
like that?

Answer 11

yeah

Answer 12

I think it is question based on triangle properties where:

\(A + B + C = 180^{\circ}\)
