60–62. {Use of Tech} Multiple tangent lines Complete the following steps. <IMAGE>
b. Graph the tangent lines on the given graph.
4x³ =y²(4−x); x=2 (cissoid of Diocles)

Verified step by step guidance

1. Identify the given equation of the curve: \(4x^3 = y^2(4-x)\). This is known as the cissoid of Diocles.
2. To find the tangent line at a specific point, we need to determine the derivative of the curve with respect to \(x\). Start by differentiating both sides of the equation implicitly with respect to \(x\).
3. Apply implicit differentiation: Differentiate \(4x^3\) to get \(12x^2\) and differentiate \(y^2(4-x)\) using the product rule, which gives \(2y \frac{dy}{dx} (4-x) - y^2\).
4. Set the derivatives equal: \(12x^2 = 2y \frac{dy}{dx} (4-x) - y^2\). Solve for \(\frac{dy}{dx}\) to find the slope of the tangent line.
5. Substitute \(x = 2\) into the derivative to find the slope at this point. Then, use the point-slope form of a line, \(y - y_1 = m(x - x_1)\), where \(m\) is the slope and \((x_1, y_1)\) is the point on the curve, to write the equation of the tangent line.

Key Concepts

Tangent Lines

A tangent line to a curve at a given point is a straight line that touches the curve at that point without crossing it. The slope of the tangent line represents the instantaneous rate of change of the function at that point, which can be found using the derivative. Understanding how to calculate and graph tangent lines is essential for analyzing the behavior of functions.

Derivatives

The derivative of a function measures how the function's output value changes as its input value changes. It is a fundamental concept in calculus that provides the slope of the tangent line at any point on the curve. To find the derivative, various rules such as the power rule, product rule, and chain rule can be applied, depending on the function's form.

Graphing Techniques

Graphing techniques involve plotting points, lines, and curves on a coordinate plane to visually represent mathematical functions and their properties. When graphing tangent lines, it is important to accurately determine the point of tangency and the slope derived from the derivative. This visual representation aids in understanding the relationship between the function and its tangent lines.
