Understanding the Concept
What is a Tangent Line?
A tangent line is a straight line that touches a curve at a single point. It provides information about the slope of the curve at that specific point.
Equation of a Tangent Line
The equation of a tangent line can be determined using the following formula:
y - y_1 = m(x - x_1)
where:
(x_1, y_1)is the point on the curve where the tangent line touches.mis the slope of the tangent line, which is equal to the derivative of the function at(x_1, y_1).
Finding the Equation of a Tangent Line
Step 1: Find the Slope
The first step involves calculating the derivative of the function at the given point. This gives us the slope of the tangent line.
Step 2: Determine the Tangent Point
Next, we need to identify the point on the curve where the tangent line touches. This is the point where the derivative is taken.
Step 3: Plug in Values
Once we have the slope and the tangent point, we can plug these values into the equation of the tangent line to solve for the equation.
