Question

help me plz!!

Answer 1

if tan(alpha+beta)=a+b and tan(alpha-beta)=a-b
prove that
atan(alpha)-btan(beta)=a^2-b^2

Answer 2

what math is that?

Answer 3

if
\[\tan(\alpha+\beta)=a+b\]
and
\[\tan(\alpha-\beta)=a-b\]
prove that
\[atan \alpha-btan \beta=a^2-b^2\]

Answer 5

i guess you can use the following tan identities

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



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

Answer 6

after that?
