i hope this help you out ;)
Answer:
54/3-7=11
Step-by-step explanation:
x/3<u>-7=11</u>
+7 +7
(3)x/3=18(3)
x=54
Check
54/3-7=11
18-7=11
11=11
I'll write "x" instead theta.
sin x + 1 = cos(2x)
formula: cos(2x) = 1 - 2sin²x
sin x + 1 = 1 - 2sin²x
2sin²x + sin x = 0
sin x (2sin x + 1) = 0
sin x = 0 or sin x = -1/2
x1 = πk and x2 = -π/6 + 2πk and
x3 = 5π/6 + 2πk
for domain 0≤x<2π :
x1 = 0 (for k=0 in x1)
x2 = π (for k=1 in x1
x3 = 11π/6 (for k=1 in x2)
x4 = 5π/6 (for k=0 in x3).
k is an integral.
I assume you mean 
, and not 
, since this doesn't satisfy the ODE.
Assume a second solution of the form 
, where 
is a function of 
. Then
Substituting into the ODE gives
where we omit the second term because it's already accounted for by 
.
