Verified step by step guidance1
Step 1: Begin by rewriting the given integral for clarity. The integral is ∫(3 - y^2) / (2y) dy. Split the fraction into two separate terms: ∫(3 / (2y)) dy - ∫(y^2 / (2y)) dy.
Step 2: Simplify each term. For the first term, 3 / (2y) simplifies to (3/2)(1/y). For the second term, y^2 / (2y) simplifies to y / 2. The integral now becomes ∫(3/2)(1/y) dy - ∫(y/2) dy.
Step 3: Integrate each term separately. For the first term, ∫(3/2)(1/y) dy, use the rule ∫(1/y) dy = ln|y|. This gives (3/2)ln|y|. For the second term, ∫(y/2) dy, use the power rule ∫y^n dy = y^(n+1)/(n+1). Here, n = 1, so the result is (1/2)(y^2/2) = y^2/4.
Step 4: Combine the results of the two integrals. The integral becomes (3/2)ln|y| - (1/4)y^2 + C, where C is the constant of integration.
Step 5: Verify the solution by differentiating the result. Differentiate (3/2)ln|y| - (1/4)y^2 + C to ensure it matches the original integrand (3 - y^2) / (2y). This confirms the solution is correct.
