Math.sin(45 * Math.PI/180) is the same as Math.sin(.7854) Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU...
Teachers often say, “My students just don’t remember what they learned last week!!!” But research shows that often many students did not actually learn the content last week, so of course they cannot remember what they did not learn. There is an enormous amount of research literature ...
Note that this expression should hold true for all valid input values x. The final question to be settled is, “What is the correct value of C to use in testing?” Because we interpret C as the number of ULP errors allowed, C is an integer of order 1. We set ...
This is exactly what the unit function does in Category Theory—it takes a value from a plain type and puts it into a monadic type. class Maybe(Generic[T]): def __init__(self, value: Optional[T]): self.value = value Creating a Monadic Value: When you create an instance of Maybe,...

What is an Equation? Definition: A mathematical expression with an equal symbol is called an equation. Algebra is frequently used in equations. When you don’t know the exact number in a calculation, you’ll need to use algebra. An equal symbol (=) must appear in an equation. In the ...
For instance, if is a mass (having the units ) and is a speed (having the units ), then it is physically “legitimate” to form an expression such as , but not an expression such as or ; in a similar spirit, statements such as or are physically meaningless. This combines well with...
Divided as the verb, so 2/2 equals 1, for example. Divided by is that dot line dot symbol. 2/2 equals 1. You can use "divided by", is the expression, two divided by... 5. Equal. Equal or equals, we use this before we present the solution to a math problem, so 2 times 2...
