Question

Kindly confirm please..
Is tan^2 (3x-1) tan3x can be reduced to tan^3 (9x^2 - 3x) ??

Answer 1

is
tan^2 (3x-1) tan3x
=tan^2 (3x-1) tan(3x) ? or
=tan^2 (3x-1) tan^3(x) ?

Answer 2

the first one. :D

Answer 3

then it's reduced down as much as it can be,
the only way you could do the tan^3 is if all the angles were the same, and if they were all the same, then it would look like: tan^3(3x-1)
make sense?
