(a) Explanation Given information : The function cos x + y = 5 . Formula used: Power Rule for differentiation, d d x ( x n ) = n x n − 1 . Calculation : Consider the function cos x + y = 5 . Differentiate both sides with respect to x , d d x ( cos x + y ) = d d x ( 5 ) d d x ( cos x + y 1 2 ) = d d x ( 5 ) Since y is a function of x , apply the Power Rule for differentiation for the term y 1 2 Recall the Power Rule for differentiation, d d x ( x n ) = n x n − 1 (b) To determine To calculate : The equation cos x + y = 5 explicitly for y and differentiate to obtain y ' in terms of x . (c) To determine To verify : The solutions obtained in part (a) and (b) are consistent by substituting the expression for y into solution of part (a).

Minimization

In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in ter…

Maxima and Minima

The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.

Derivatives

A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which …

Concavity

In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the …
