Q:
# What is the Lagrange remainder?

A:
### Quick Answer

The Lagrange remainder is a term that estimates the size of the error introduced by a partial sum of the Taylor series when it is used to compute an approximated value for the original function. The Lagrange remainder for the Taylor series is a tool not only for estimating errors but for giving a precise difference between the polynomial and the original function approximated by the polynomial.

Continue ReadingThe Lagrange remainder may sometimes refer to the remainder when terms in the Taylor series are taken up the second last power. Lagrange's remainder is applicable to the binomial series studied by Jean d'Alembert, as it provides solutions to pertinent questions such as, determining what happens when X is equal to one. It also provides accurate answers as to the exact number of terms that must be taken when a series converges for the attainment of the desired accuracy.

It also clarifies on the degree of accuracy, which can be obtained once a series diverges. The Lagrange remainder is one of the various forms of the Taylor series remainder, while other explicit forms of the remainder include the mean-value forms and the Cauchy form. These forms are refinements of the Taylor theorem and are typically proven using the mean value theorem.

Q:
## What is the integral of the secant function?

A:The integral of the secant function is the natural logarithm of the absolute value of the secant of x plus the tangent of x, plus a constant. Expressed in mathematical notation, it reads as the integral of sec x dx = ln |sec x + tan x| + C.

Q:
## What is cot x equal to?

A:"Cot" is the abbreviation for "cotangent," a trigonometric function used to find the value of an angle in a right triangle by dividing the length of an adjacent side by the length of the opposite side. The numerical value of cot x varies depending on the value of x.
