- Compute the directional derivative in the direction of v at the given point. f(x, y) = e*y-y, v = (12, –5), P = (-1,–1) Remember to use a unit vector in your directional derivative computation. (Give an exact answer. Use symbolic notation and fractions where needed.) Duf(-1, –1) =arrow_forwardCompute the directional derivative in the direction of v at the given point. S(x. y) = xy - x, v=i-j, P= (-1,2) Remember to use a unit vector in your directional derivative computation. (Give an exact answer. Use symbolic notation and fractions where needed.) Du f(-1,2) =arrow_forwardMotion around a circle of radius a is described by the 2D vector-valued function r(t) = ⟨a cos(t), a sin(t)⟩. Find the derivative r′ (t) and the unit tangent vector T(t), and verify that the tangent vector to r(t) is always perpendicular to r(t).arrow_forward
