- in 81: Separate the variables for the differential equation d = and then integrate each m a: side. 1} Fill in your integrands {starting with the left-handside) before integrating both sides. [SEEP/Eda: 2} Integrate both sides of the equation in part (1}. Do not solve for y yet. Use the lowercase c as an arbitrary constant or pick it up from the Uars tab. 3} Finally, solve for y explicitly. Use the lowercase k as an arbitrary constant or pick it up from the Wars tab: W) = E
