It is borrowed from computer programming: it means that the item on the left hand side is being defined to be what is on the right hand side. For example, y:= 7x + 2 y := 7 x + 2. means that y y is defined to be 7x + 2 7 x + 2. This is different from, say, writing. 1 =sin2(θ) +cos2(θ) 1 = sin 2 ( θ) + cos 2 ( θ)Example: speed and travel time. Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written:There is another concept related to complex number that is based on the following bit of algebra. (a + bi)(a − bi) = a2 − (bi)2 = a2 − b2i2 = a2 + b2. The complex number a − bi is called the complex conjugate of a + bi. If we let z = a + bi, we denote the complex conjugate of z as ˉz. So ˉz = ¯ a + bi = a − bi.

A residue class modulo n n is the set of all integers which give the same rest when divided by n n. There are exactly n n residue classes, corresponding to the n n reminders on division by n n, 0 0 to n − 1 n − 1. The key point is that the reminder of ... mike leitchlowes drop in bathroom sink B is the divisor. Q is the quotient. R is the remainder. Sometimes, we are only interested in what the remainder is when we divide A by B . For these cases there is an operator called the modulo operator (abbreviated as mod). Using the same A , B , Q , and R as above, we would have: A mod B = R. craigslist gulfport boats for sale by owner There are just a few common examples of where you might see Greek letters.
