Answer:
nn
Step-by-step explanation:
Answer:y=
Acosx+Bsinx +cosx ln(cosx)+x sinx
Step-by-step explanation:
given equation y''+y=secx
auxiliary equation

so CF is y=Acosx+Bsinx
now

using wronskian formula

=
now f(x)=secx




now particular integrals are
PI=cosx ln(cosx)+x sinx
total solution
y= C.F+P.I
y=Acosx+Bsinx +cosx ln(cosx)+x sinx
Your description and expansion suggest you want to evaluate
.. 246₈ = 2*8² +4*8¹ +6*8⁰
.. = 2*64 +4*8 +6
.. = 166
