# Math Help - Simplifying trigonometric expressions

1. Ok so:

sin^3 $\theta$ - cos^3 $\theta$
------------------
sin^2 $\theta$ - cos^2 $\theta$

=

sin^2 $\theta$-sin $\theta$cos $\theta$ + cos^2 $\theta$
--------------------------
sin $\theta$ + cos $\theta$

=

1+sin $\theta$cos $\theta$
----------------
sin $\theta$ + cos $\theta$

EDIT: Sorry! I realised i factorised it wrong! But the book still says it's wrong! Don't worry though, I think the book is wrong, thanks for te enormous help!
