The diamond ones you multiply the two sides to get the top number and add the two sides to get the bottom. If the number are in other stops besides the two sides you must find a solution that works with the corresponding numbers. I’m not really sure about the rest. Good luck with that!

Suppose f(x, y) is a differentiable function of x and y and let g(r, s) = f (2rs, 8s − 2r). Use
worty [1.4K]

By the chain rule,

\dfrac{\partial g}{\partial r} = \dfrac{\partial f}{\partial r} \\\\ ~~~~~ = \dfrac{\partial f}{\partial x} \dfrac{\partial x}{\partial r} + \dfrac{\partial f}{\partial y} \dfrac{\partial y}{\partial r} \\\\ ~~~~~ = 2 s \dfrac{\partial f}{\partial x} - 2 \dfrac{\partial f}{\partial y}

where x(r,s)=2rs and y(r,s)=8s-2r.

If r=2 and s=1, then

x = 2\cdot2\cdot1 = 4

y=8\cdot1-2\cdot2 = 4

so that

g_r(2,1) = 2\cdot1 f_x(4,4) - 2 f_y(4,4) = 2\cdot2-2\cdot3 = \boxed{-2}

1. Write the equation for a line in point slope form that had a slope of 4 and passes through (1,1)
Dahasolnce [82]

Solution:

<u>Note that:</u>

  • Slope = m = 4
  • Given point: (x₁,y₁) = (1,1) [x₁ = 1; y₁ = 1]
  • Formula: y - y₁ = m(x - x₁)

<u>Use the formula to convert the line in point slope form.</u>

  • y - y₁ = m(x - x₁)
  • y - 1 = 4(x - 1)

The equation of the line (In point slope form) is y - 1 = 4(x - 1).
