$-\frac{1}{2}y^{\left(-\frac{1}{2}-1\right)}$
Learn how to solve integral calculus problems step by step online. Find the derivative d/dy(y^(-1/2)) using the power rule. The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}. Subtract the values -\frac{1}{2} and -1. Applying the property of exponents, \displaystyle a^{-n}=\frac{1}{a^n}, where n is a number.
