Q. A curve is defined by the parametric equations x(t)=7t3 and y(t)=t2−2t−5. Find dxdy.Answer:
Identify Derivatives: To find (dxdy), we first need to find the derivatives of x(t) and y(t) with respect to t, which are denoted as dtdx and dtdy, respectively.
Calculate dtdx: Calculate dtdx, which is the derivative of x(t) with respect to t. dtdx=dtd(7t3) dtdx=21t2
Calculate dtdy: Calculate dtdy, which is the derivative of y(t) with respect to t. dtdy=dtd(t2−2t−5) dtdy=2t−2
Find (dxdy):</b>Now,tofind$(dxdy),wedivide$dtdy by dtdx.(\frac{dy}{dx}) = \frac{(\frac{dy}{dt})}{(\frac{dx}{dt})}\(\newline(\frac{dy}{dx}) = \frac{(\(2\)t - \(2\))}{(\(21\)t^\(2\))}
Simplify the Expression: Simplify the expression for \((\frac{dy}{dx}).(dxdy)=21t22t−2(dxdy)=21t22(t−1)
