Finding the Normal Line from Parametric Equations
Consider the parametric functions \(x(t) = t^2 + 1\) and \(y(t) = 2t – 3\). At \(t = 2\), find the slope of the normal line to the curve and provide its equation.
Parametric Functions: Analyzing Increasing and Decreasing Intervals
Given the parametric equations \( x(t) = t^2 – 4t \) and \( y(t) = t^3 – 6t^2 + 9t \), determine the intervals of the parameter \( t \) over which the curve is increasing and decreasing with respect to \( x \) by analyzing the signs of \( \frac{dx}{dt} \) and \( \frac{dy}{dt} […]
Parametric Exploration in Radian Domain
Investigate the parametric functions defined by \(x(t)=r\cos(t)\) and \(y(t)=r\sin(t)\) where the angle \(t\) is measured in radians. In this problem, you will: (a) Explore how these functions represent a circle and the importance of using radians. (b) Analyze how varying the parameter \(r\) impacts the graph and arc length of the circle. (c) Interpret the […]
