\[\large \frac{\sin 2\theta}{2} \ne \sin \theta \]

OpenStudy (anonymous):

ah yes i forgot.

ganeshie8 (ganeshie8):

looks good, put it in standard form and do the regular stuff

OpenStudy (anonymous):

dp/dtheta+ p costheta= sin2theta/2

ganeshie8 (ganeshie8):

\[\large p' + (\cos\theta)p = \frac{\sin (2\theta)}{2}\]

ganeshie8 (ganeshie8):

\(IF = e^{\int \cos\theta d\theta}\)

OpenStudy (anonymous):

e^sintheta

ganeshie8 (ganeshie8):

yes keep going :)

OpenStudy (anonymous):

i take out 1/2 from the right side

ganeshie8 (ganeshie8):

yes

ganeshie8 (ganeshie8):

write \(\sin(2\theta)\) as \(2\sin\theta \cos\theta\) and substitue \(u = \sin\theta\)
