What are the two domain view of the universe?

What are the two domains of universe according to Greeks? Aristotle posited that there were two separate realms in the cosmos, the terrestrial (or earthly) and the celestial (or heavenly). Everything in the terrestrial realm was made up of four elements: earth, water, air and fire. What are the elements of celestial domain? The terrestrial

Is cosh even or odd?

Thus, cosh x and sech x are even functions; the others are odd functions. the last of which is similar to the Pythagorean trigonometric identity. for the other functions. Are sinh and cosh odd or even? and the hyperbolic sine is the function sinhx=ex−e−x2. Notice that cosh is even (that is, cosh(−x)=cosh(x)) while sinh is

Why must astronomers have a thorough understanding of light?

When stargazers go outside at night to look at the sky, they see the light from distant stars, planets, and galaxies. Light is crucial to astronomical discovery. Whether it’s from stars or other bright objects, light is something astronomers use all the time. Human eyes “see” (technically, they “detect”) visible light. How does light play

Is cork fabric durable?

Cork Fabric: Durable and Longlasting Cork is a sturdy material that holds up over time and, like leather, ages beautifully. It’s also known to be water- and stain-resistant, and it won’t scratch. What is cork fabric good for? Use it to make handmade bags, wallets, accents on clothing, craft projects, applique, embroidery, shoes, or upholstery.

What is difference between roundness and circularity?

Roundness is independent of any datum feature and only is always less than the diameter dimensional tolerance of the part. Circularity essentially makes a cross-section of a cylindrical or round feature and determines if the circle formed in that cross-section is round. Is roundness and circularity same? Is it called roundness or circularity? The terms

What is the best fertilizer for calla lilies? Incorporate well-rotted compost, bone meal, or cow manure into the soil

What is chain rule in differentiation?

The chain rule states that the derivative of f(g(x)) is f'(g(x))⋅g'(x). In other words, it helps us differentiate *composite functions*. For example, sin(x²) is a composite function because it can be constructed as f(g(x)) for f(x)=sin(x) and g(x)=x². What is meant by chain rule? : a mathematical rule concerning the differentiation of a function of

What is the derivative of tan 2?

2x”>2 sec2x2x is dy/dx = 2 sec2x tan x. What is the derivation of tan 2x? The derivative of tan 2x is twice the square of secant function with angle 2x, that is, 2 sec2(2x). Mathematically, the derivative of tan 2x is written as d(tan 2x)/dx = 2 sec2(2x) or (tan 2x)’ = 2 sec2(2x).
