When the following functions are evaluated atvalues of x that are close to 0 there will be aloss of significant digits of accuracy. For eachfunction: (i) use identities or Taylor series approximationsto find an alternative representationof the function that avoids cancellation of significantdigits, (ii) use a hand calculator or computerto evaluate the function by plugging in thevalue x = 10−8 and also evaluate the alternativerepresentation of the function at the pointx = 10−8. : f (x) = sec x − cos x
Optimization
Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.
Integration
Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.
Application of Integration
In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.
Volume
In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).
Area
Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
When the following functions are evaluated at
values of x that are close to 0 there will be a
loss of significant digits of accuracy. For each
function: (i) use identities or Taylor series approximations
to find an alternative representation
of the function that avoids cancellation of significant
digits, (ii) use a hand calculator or computer
to evaluate the function by plugging in the
value x = 10−8 and also evaluate the alternative
representation of the function at the point
x = 10−8. : f (x) = sec x − cos x
