Solved: Finding a Directional Derivative In Exercises 14, use Theorem 13.9 to find the
Chapter 13, Problem 3(choose chapter or problem)
In Exercises 1 - 4, use Theorem 13. 9 to find the directional derivative of the function at P in the direction of the unit vector \(u=\cos \theta i+\sin \theta j\).
\(f(x, y)=\sin (2 x+y), \quad P(0,0), \quad \theta=\frac{\pi}{3}\)
Text Transcription:
u = cos theta i +sin theta j
f(x, y) = sin (2x + y), P(0, 0), theta = pi / 3
