When the upper and lower dental formulae are the same, some texts write the formula without a fraction ( in this case, 2. 1. 2. 3 ), on the implicit assumption that the reader will realise it must apply to both upper and lower quadrants.

When the same roots occur multiple times, the terms in this formula corresponding to the second and later occurrences of the same root are multiplied by increasing powers of n. For instance, if the characteristic polynomial can be factored as ( x − r )< sup > 3 </ sup >, with the same root r occurring three times, then the solution would take the form

When feedback is present the so-called closed-loop gain, as shown in the formula of the previous section, becomes,

When part of a salt, the formula of the acetate anion is written as CH < sub > 3 </ sub > CO < sub > 2 </ sub >< sup >−</ sup >, C < sub > 2 </ sub > H < sub > 3 </ sub > O < sub > 2 </ sub >< sup >−</ sup >, or CH < sub > 3 </ sub > COO < sup >−</ sup >.

When one of the parallel sides has shrunk to a point ( say a = 0 ), this formula reduces to Heron's formula for the area of a triangle.

When a question contains two verbs, the response does not make clear which of them is being answered.

When a Java technology-enabled web browser processes a page that contains an applet, the applet's code is transferred to the client's system and executed by the browser's Java Virtual Machine ( JVM ).

When all of the sound, picture, and data elements of a production have been completed, they may be assembled into a Digital Cinema Distribution Master ( DCDM ) which contains all of the digital material needed for projection.

When a vertex v is added, we split in three the triangle that contains v, then we apply the flip algorithm.

When a granitoid contains less than 10 % orthoclase, it is called tonalite ; pyroxene and amphibole are common in tonalite.

When inspired air contains CO levels as low as 0. 02 %, headache and nausea occur ; if the CO concentration is increased to 0. 1 %, unconsciousness will follow.

When one reactant contains hydrogen atoms, a reaction can take place by exchanging protons in acid-base chemistry.

When first connected to a network, a host sends a link-local router solicitation multicast request for its configuration parameters ; if configured suitably, routers respond to such a request with a router advertisement packet that contains network-layer configuration parameters.

When James Cook went on his first voyage he carried wort ( 0. 1 mg vitamin C per 100 g ), sauerkraut ( 10 – 15 mg per 100 g ) and a syrup, or " rob ", of oranges and lemons ( the juice contains 40 – 60 mg of vitamin C per 100 g ) as antiscorbutics, but only the results of the trials on wort were published.

* Kenneth Rexroth's One Hundred Poems from the Japanese ( New Directions, 1955, ISBN 0-8112-0181-3 ) contains several of Hitomaro's waka, as well as notable translations of 3 naga uta (" In the sea of ivy clothed Iwami ", " The Bay of Tsyunu ", and " When she was still alive ")

" When Batman confronts Rohtul, he has one of his robots open a compartment that contains Quartz.

Effect of a magnet on the domains. When a domain contains too many molecules, it becomes unstable and divides into two domains aligned in opposite directions so that they stick together more stably as shown at the right.

When contains many candidate functions or the training set is not sufficiently large, empirical risk minimization leads to high variance and poor generalization.

When the biological significance of nicotinic acid was realized, it was thought appropriate to choose a name to dissociate it from nicotine, to avoid the perception that vitamins or niacin-rich food contains nicotine, or that cigarettes contain vitamins.

When a domain is registered with a domain name registrar, the zone administrator provides a list of name servers ( typically at least two, for redundancy ) that are authoritative for the zone that contains the domain.

When reactive elements such as capacitors, inductors, or transmission lines are involved in a circuit to which AC or time-varying voltage or current is applied, the relationship between voltage and current becomes the solution to a differential equation, so Ohm's law ( as defined above ) does not directly apply since that form contains only resistances having value R, not complex impedances which may contain capacitance (" C ") or inductance (" L ").
