Hello, I am looking at the differential equation:
dR/DΘ + R = e^-Θ * sec^2Θ
I understand how to use e^(integral of e^(1dΘ) to multiply both sides which gives me:
(looking at left hand side of equation only)
e^Θ * dR/dΘ + e^Θ * R
However I am not sure how to further simplify the left hand side of the equation before integrating.
Can someone please show me the process for doing that.
Thanks kindly for any help.
