Answer:
Step-by-step explanation:
Given differential equation and initial condition:
Rearrange the differential equation so that all the terms containing y are on the left-hand side, and all the terms containing x are on the right-hand side:
Integrate both sides of the equation:
Substitute the given condition y(-π) = 0 into the equation and solve for C:
Substitute the found value of C into the equation:
Multiply both sides by -1:
