• 01:3701:37, 19 May 2022 diff hist +466‎ N Finding extreme values of a multivariable function ‎ Created page with "The general idea is analogous to single variable functions. Whether we are discussing the function's domain or a subdomain of it, we have to use derivatives to analyse how the function behaves to know whether a point is a maximum or a minimum. For two variables the idea is the same as for one variable, in a certain interval the function ca be constant, crescent or decrescent. For three and more variables we lose the function's graph, but the algebra is the same."

• 01:5001:50, 9 May 2022 diff hist +257‎ N Chain rule for multivariable functions ‎ Created page with "With a single variable function the chain rule tells us that <math>[f(g(x))]' = g'(x)f'(g(x))</math>. For multivariable functions the idea is the same, it's still a product of derivatives. Both functions have to be differentiable for the chain rule to work."

In the same way that zooming in a function of one variable makes it render closer to a straight line, with a tangent plane we see that the level curves become closer to straight parallel lines if we zoom in enough. <div style="text-align:center;"> 600px ''(not to scale)'' </..."
