Calculus: Early Transcendentals

The Gateway Arch in St. Louis was designed by Eero Saarinen and was constructed using the equation
$ y = 211.49 - 20.96 \cosh 0.03291765x $
for the central curve of the arch, where $ x $ and $ y $ are measured in meters and $ \mid x \mid \le 91.20. $
(a) Graph the central curve.
(b) What is the height of the arch at its center?
(c) At what points is the height $ 100 m? $
(d) What is the slope of the arch at the points in part (c)?

Integration Review

Integration Review - Intro

In mathematics, integration is one of the two main operations in calculus, with its inverse, differentiation, being the other. Given a function of a real variable, an antiderivative, integral, or integrand is, loosely speaking, a formula that describes the function. Integration is the inverse operation to differentiation. The integration of a function "f"("x") is its indefinite integral denoted by ?"f"("x")dx.

Definite vs Indefinite

In grammar, determiners are a class of words that are used in front of nouns to express how specific or non-specific the noun is. A specific noun is one that can be identified in a unique way from other things. For example, "the cat" is a specific noun, while "a cat" is an indefinite noun, because it is not clear if it is the same cat that was already mentioned, or another cat.

Trig Integrals

In mathematics, a trigonometric integral is an integral of a function of one variable, often trigonometric functions, over a closed interval of length 2?. The function must be piecewise continuous and must be zero at the endpoints of the interval. Such integrals are used in the definition of the Fourier series, and are also useful in many other applications. The most important case is the case of the Fourier series, where the integral is the Fourier integral, and is the basis for the Fourier transform.

Area Between Curves

Area Between Curves - Intro

The area between two curves in the plane is the region bounded by the curves and the x-axis. The area of a region bounded by two curves and an axis of symmetry is the area of the region on one side of the axis of symmetry, minus the area of the region on the other side of the axis of symmetry.
