Solving an Optimization Problem using Implicit Differen tiation Suppose you wish to build a grain silo with volume V made up of a steel cylinder and a hemispherical roof. The steel sheets covering the surface of the silo are quite expensive, so you wish to minimize the surface area of your silo. What

Implicit differentiation is needed to find the slope. Therefore [ ] ( ) ( ) Hence, the tangent line is the vertical line Example 4 Find 5 =for The trick here is to multiply both sides by the denominator Thus we implicitly differentiate ( Now you try some: )( ) ( ) Hence, 25 2

Implicit Differentiation mc-TY-implicit-2009-1 Sometimes functions are given not in the form y = f(x) but in a more complicated form in which it is difficult or impossible to express y explicitly in terms of x. Such functions are called implicit functions. In this unit we explain how these can be differentiated using implicit differentiation.

Differentiation of implicit functions Fortunately it is not necessary to obtain y in terms of x in order to differentiate a function defined implicitly. Consider the simple equation xy = 1 Here it is clearly possible to obtain y as the subject of this equation and hence obtain dy dx.

of the graph at x = 2 directly by differentiating f. Then use the implicit differentiation method and differentiate y2 = x2−x assuming y(x) is a function of x and solving for y′. 2 The equation x2 +y2 = 5 defines a circle. Find the slope of the tangent at (1,2). 3 The equation x100+y100 = 1+2100 defines a curve which looks close to a ...

with the implicit di erentiation formula, so the added cost of using both coordinates x and y in an implicit di erentiation formula for dy=dx is worth it. Finding tangent lines to curves like y2+xy = x3+x2+1 is not a pointless exercise: this kind of math is used inelliptic curve cryptography(ECC), which is one of the
