How do I simplify 2sinxcosx?
I'm confused as to what it is I'm supposed to simplify. Thanks for any help...
Answer :
Probably you're supposed to work off this identity:
sin(a + b) = sina cosb + cos a sinb
Therefore
sin(a + a) = sina cos a + cos a sin a = 2sinacosa
2sinxcosx = sin(x + x) = sin2x

i hope i can help you now, thank
