Final answer:
A tangent line calculator involving composite functions and matrix slope determines the slope of a curve at a specific point.
Step-by-step explanation:
A tangent line calculator involving composite functions and matrix slope determines the slope of a curve at a specific point. The slope of a curve at a point is equal to the slope of a straight line tangent to the curve at that point. The calculator uses the concept of composite functions to find the slope of the tangent line by finding the endpoints of the tangent line and plugging them into the equation.
