LFad belagth of the paractric corve

It seems like there might be a typo in your question. If you're asking about the "length of the parametric curve," I can help with that! To find the length of a parametric curve defined by the equations \( x(t) \) and \( y(t) \) over an interval \( [a, b] \), you can use the following formula: \[ L = \int_a^b \sqrt{\left( \frac{dx}{dt} \right)^2 + \left( \frac{dy}{dt} \right)^2} \, dt \] Here, \( \frac{dx}{dt} \) and \( \frac{dy}{dt} \) are the derivatives of \( x(t) \) and \( y(t) \) with respect to \( t \). If you have specific functions for \( x(t) \) and \( y(t) \) and a specific interval, please provide them, and I can help you calculate the length of the curve!
