Answer:
Explanation:
The witches gather on the moor and cast a spell as Macbeth and Banquo arrive. The witches hail Macbeth first by his title Thane of Glamis, then as Thane of Cawdor, and finally asking. They then prophesy that Banquo's children will become kings. Macbeth demands to know more but the witches vanish.
Morosely means "not cheerful" or "gloomy". That would be my definition.
The mathematical concepts that Leonhard Euler's legacy included are as follows:
The formalization of function notation
The notation for the imaginary unit
The notation for the base of the natural logarithm
Remember, that all of Euler's legacy included the introduction of the concept of functions as well as the proper way to write them within a mathematical formula by using the notation f(x). Before his formalization of the notation, functional relationships were referred to by just one letter, F, or with Greek letters omitting the parentheses, φx. In fact, Euler spelled out much of the mathematical notation we use today, including the letter "e" for the base of the natural logarithm (also known as Euler's number), the letter "I" to denote the imaginary unit, and the Greek letter "Σ" for summations. He also encouraged the use of the Greek letter "π" to signify the ratio of a circle's circumference to its diameter.
