Question

can anyone help me with this
2sintcost - cost = 0
im probably overthinking this

Answer 1

2 sin(t) cos(t) = sin(2t)

when does sin(2t) = cos(t)?

Answer 2

factor out the cos

Answer 3

or...do it the smart way and factor out the ...... lol

Answer 4

your way works too

Answer 5

sint(cost+sint)?

Answer 6

cos(t)(2sin(t) - 1) = 0 when does cos(t) = 0? 90 and 270 right?

Answer 7

2sin(t) - 1 = 0

2sin(t) = 1

sin(t) = 1/2...thats a 30 right? and 150?

Answer 8

k, i knew i had to factor out, just didnt know where to start
