Change along the involute of a circle Find the derivative
Chapter 13, Problem 56E(choose chapter or problem)
Change along the involute of a circle Find the derivative of \(f(x, y)=x^{2}+y^{2}\) in the direction of the unit tangent vector of the curve
\(r(t)=(\cos t+t \sin t) i+(\sin t-t \cos t) j, \ \quad t>0\)
Equation Transcription:
f(x, y) = x2 + y2
r(t) = (cos t + t sin t)i + (sin t - t cos t)j, t >0
Text Transcription:
f(x, y) = x^2 + y^2
r(t) = (cos t + t sin t)i + (sin t - t cos t)j, t >0
