Question 145207: Hello (again),
Please disregard the first question sent to you from (kenronda@sover.net).
After thinking about my question I relized it was flawed in a few ways.
Also, I mis-quoted the text I was working from. (sorry mr. text)
If you would allow me to re-phrase my question:
Problem: (solve: 2cosx + sin2x = 0)
I used the Double-Angle Identity to make (sin2x) ---> (2sinxcosx)
Can I view a term that looks like this: (2sinxcosx)
as: (2)(sinx)(cosx) -----> (sinx)(2)(cosx) ?????????
If this is legal it would let me Factor out the (2)(cosx) from the
original problem and solve each Factor for the Solution Set.
Thank you for your help-- ken b
You can put this solution on YOUR website! Ken, I saw that first post and could not get it past 2cosx (1 + sinx)
You also asked for a good source for identities. I like this one. http://mathforum.org/dr.math/faq/formulas/faq.trig.html
