Solve the given initial-value problem. Write the solution as an explicit algebraic function $y=f(x)$ (see Notes From the Classroom in Section 1.3). You may have to use a trigonometric identity.
$\sqrt{1-x^{2}} \frac{d y}{d x}=\sqrt{1-y^{2}}, \quad y(0)=\frac{\sqrt{3}}{2}$

Key Concepts

Trigonometric Identities

Trigonometric identities are often used to simplify integrals involving square roots or other expressions that resemble trigonometric forms. These identities help in converting the integrals into forms that are easier to evaluate, and they facilitate the manipulation needed to express the solution explicitly.

Integration Techniques and Antiderivatives

Integrating the resulting separated expressions requires knowledge of antiderivatives and sometimes specific techniques such as trigonometric substitution. Recognizing integral forms and applying the appropriate antiderivative is fundamental to solving the equation.

Initial Value Problem

An initial value problem (IVP) involves solving a differential equation along with a given condition that specifies the solution's value at a particular point. This condition ensures the uniqueness of the solution within a specific domain and helps in determining any arbitrary constants that may arise during integration.

Separable Differential Equation

A separable differential equation is one that can be rewritten so that all terms involving the dependent variable are on one side of the equation and all terms involving the independent variable are on the other. This separation allows the problem to be systematically solved by integrating both sides independently.

Separation of Variables

The method of separation of variables involves rearranging the differential equation to isolate differentials of the dependent and independent variables on opposite sides of the equation. Once separated, each side is integrated, yielding an implicit solution that can often be manipulated into an explicit function form.
