Question

Algebra Question. Please help if you can! I really appreciate it so much! ^-^

Answer 1

Ok so what is the first thing you have to do?

Answer 2

Write out what I know. x would be 1-5 correct? So I would plug one of those values in for x?

Answer 3

Yes

Answer 4

y = 5 sin x +3 sin x cos x

so like a first step how you make from this equation to be just one and not two unknown terms ?

rewrite the cos x in te form of sin x

do you know the way ?

You simplify it so you would combine 5 sin x and 3 sin x, which would be 8 sin x... right?

Answer 6

no

like a first step you need rewrite the cos x using sin x

just to have there in this equation just sin x

and in this way will be the next step to note the sin x with an t and solve this equation for t

when you solved and get the roots in function of t so than you need reconvert these roots back from t in sin x

hope can you understand me

Answer 7

@darkknight do you agree it ?
