    Find F(2,4) of Differentiable Function

    Agreed, a = <3,4> therefore magnitude would be 5 if a =<2,4> magnitude would be 2rt(5) thanks

    Find F(2,4) of Differentiable Function

    i think i got it. grad (f) doted with unit

    Find F(2,4) of Differentiable Function

    I didn't know. here is what i have so far... i know that the gradient (F) is -3i +8j i think Duf(2,4) would be same i think vector a = <3,4> to unit would be <3,4>/5

    Find F(2,4) of Differentiable Function

    let f(x,y) be a differentiable function.Given that fx(2,4) =-3 and fy(2,4) =8, find F(2,4) where u is in the same direction of a =<2,4>
