Hi, I have
[(sin^2theta) - (cos^2theta) ]/ (sin(theta) + cos(theta))
And I need to simplify it to sin(theta) - cos(theta).
How do I do that? Thanks!
The interesting thing here is that Malay would not have suggested thatOriginally Posted by classicstrings
you simply divide if he had not already recognised that the numerator
factored from the difference of two squares form that it has and that
one of these factors was the denominator.
(At least that is my take on what was going on)
