Given the equation y In (x + y + 8) = 3, evaluate Assume that the equation implicitly defines y as a differentiable function of x.
Assuming that the equation defines x and y implicitly as differentiable functions x =f(t), y =g(t), find the slope of the curve x =f(t), y=g(t) at the given value of t. x3 +41? = 37, 2y3 - 22 = 110, t = 3 The slope of the curve at t= 3 is (Type an integer or simplified fraction.)

4. Suppose you are given an equation of the form F(x, y,z) 0. Then we can say that each of the variables is defined implicitly as a function of the others. 2 a) If F and z(x, y) are both assumed to be differentiable, fnd in terms of partial derivatives of F. b) Under similar assumptions on the other variables, find 4. Suppose you are given an equation of the form F(x, y,z) 0. Then we can say that each...
Please help with this question. Thank you! 1. We say p (ro. yo, 20) is a regular point for the equation F(x, y,) 0 if the equation either defines as a differentiable function f( for (, y) in a neighborhood of (ro, Vo), or defines y as a differentiable function y-g(, a) for (r, z) in a neighborhood of (ro, 2o), or defines z as a differentiable functionh(x, y) for (x, y) in a neighborhood of (ro.o). a. Suppose p...
