When calculating the length of a short north-south line at the equator, the sphere that best approximates that part of the spheroid has a radius of, or 6, 335. 439 km, while the spheroid at the poles is best approximated by a sphere of radius, or 6, 399. 594 km, a 1 % difference.

When calculating probabilities for a card game such as Texas Hold ' em, there are two basic approaches.

When calculating the radiance emitted by a source, A refers to an area on the surface of the source, and Ω to the solid angle into which the light is emitted.

When all the measuring, comparing, and calculating are done, some type of final control element must implement the strategy selected by the controller.

When calculating the prime, a separate point scale is used.

When calculating or estimating data throughputs, the details of the frame / cell / packet format and the technology's detailed implementation need to be understood.

When calculating multiples over different time periods ( e. g. historic multiples vs forward multiples ) EV should be adjusted to reflect the weighted average invested capital of the company in each period.

When these fluctuations were explained as a manifestation of changes in atmospheric pressure, the science of meteorology was born.

When a laser light is passed through the sample in these areas, fluctuations in the sample's density cause the light to be scattered.

When it comes to nano reefs, even minute changes in water conditions such as mild temperature fluctuations can be problematic, whereas the greater water volume of larger aquariums provides a more stable and flexible environment.

When precision is too low, rounding errors affect results and small fluctuations not modeled in the simulation can drastically change the predicted results ; simulated objects can behave unexpectedly or arrive at the wrong location.

When Zatanna and Red Tornado finally resolve the crisis, Vixen goes to seek Animal Man, since he's been affected by similar power fluctuations, and left unable to tap into the powers of Earth-borne animals.

When too many entities are measured at the same time the overall fluctuations are small in comparison to the total signal and may not be resolvable – in the other direction, if the individual fluctuation-events are too sparse in time, one measurement may take prohibitively too long.

When I went for my interview with the director I saw why.

When his eyes began to focus, he saw Jess charging at him with a pitchfork.

When confronted with a drunk or an insane person I have no notion of what any one of them might do to me or to himself or to others.

When I try to work out my reasons for feeling that this passage is of critical significance, I come up with the following ideas, which I shall express very briefly here and revert to in a later essay.

When words can be used in a more fresh and primitive way so that they strike with the force of sights and sounds, when tones of sound and colors of paint and the carven shape all strike the sensibilities with an undeniable force of data in and of themselves, compelling the observer into an attitude of attention, all this imitates the way experience itself in its deepest character strikes upon the door of consciousness and clamors for entrance.

When combined with the metaphysical notion that pure forms of this universe are best appreciated when least embodied in a material substratum, it becomes clear that while earth will be dross on a scale of material-formal ratios, celestial bodies will be of a subtle, quickened, ethereal existence, in whose embodiment pure form will be the dominant component and matter will be absent or remain subsidiary.
