Question

first order lnear diff eq

Answer 1

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

Answer 2

ah yes i forgot.

Answer 3

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

Answer 4

dp/dtheta+ p costheta= sin2theta/2

Answer 5

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

Answer 6

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

Answer 7

e^sintheta

Answer 8

yes keep going :)

Answer 9

i take out 1/2 from the right side

Answer 10

yes

Answer 11

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