In general, when we are asked to find c mod n, the answer would be the remainder when c is divided by n. This simplifies things since c mod n is actually congruent to many numbers mod n. For example, if we were asked to find 14 mod 12, the answer would be 2 mod 12, because if we divide 14 by 12, we get a remainder of 2. In this case, we are working with modulus 7. Evaluate the integral and interpret it as the area of a region. (2.6 m). Track . 40 33
The number that we count up to and then start over at is called the modulus. A short summary of this paper. Take a look at this clock: Notice that the numbers on the clock go up to twelve, and then they start over. Track modulus is a measure of the vertical stiffness of the rail foundation and is defined as the ratio of the vertical supporting force per unit length of rail to the unit vertical deflection. We can see the modulus 4 concept illustrated here: It is important to note that when working in mod n, if the remainder is 0 when we divide a by n, then a mod n would be 0 mod n, not n mod n. Remember that when we are trying to find a mod n, we are just looking for the remainder when a is divided by n. For example, if we were trying to find 8 mod 4, the answer would be 0 mod 4, not 4 mod 4, because the remainder is 0 when we divide 8 by 4.
