Question

can anyone help me with understanding how to solve trig questions that go something like sinx-sinxtan3x=0

Answer 1

factor sinx out. tell me what you have?

Answer 2

1-tan3x

Answer 3

where sinx? you factor, not cancel.

Answer 4

woops

Answer 5

lol nevermind I got that one! posted wrong question

the one i need help on was sinxtan3x=0

Answer 6

so, just sinx =0 or tan 3x =0 ,

Answer 7

so, what's wrong? you cannot have cos 3x =0 since it is in denominator, so tan 3x =0 if and only if the numerator =0, what's wrong with that logic? It's standard. SURE !!!
