- A delta forms if the waves and the tide cannot carry all of the material away. Formation of a delta: A river carrying sediment reaches the sea or a lake. It loses energy and deposits material. The sediment may be sorted as the heaviest material is deposited first. Over time, more and more sediment is added.

What does delta mean in math? There are many, many situations where the actual start and end values are irrelevant or unimportant - only the difference matters. To take a household example, if a cake recipe calls for the batter to be put in the oven for, say 25 mins, what is really being told to you is the [math]\Delta T[/math]. After all, no cookbook on earth is going to say, put the batter in the oven at 11 am and take it out at 11:25am :)

Delta- v Delta-v (literally change in velocity), symbolised as ∆v and pronounced delta-vee, as used in spacecraft flight dynamics, is a measure of the impulse that is needed to perform a maneuver such as launch from, or landing on a planet or moon, or in-space orbital maneuver. It is a scalar that has the units of speed.

- Delta T is the change in temperature in air or water as it goes through a heat exchanger coil. For a constant capacity, the flow of the fluid is inversely proportional to the … delta T (i.e. as the flow of the fluid increases the delta T of the fluid decrease and vice versa). 4 people found this useful.

Delta E The E in Delta E comes from the German word Empfindung, meaning feeling, sensation. Delta comes from the Greek language, and is used in mathematics (as the symbol Δ) to signify an incremental change in a variable, i.e., a difference. So, Delta E comes to mean a difference in sensation. A Delta E of 1 between two colors that are not touching one another is is generally considered to be barely perceptible by the average human observer; a Delta E between 3 and 6 is typically considered an acceptable match in commercial reproduction on printing presses. (Note: Human vision is more sensitive to color differences if two colors actually touch each other.) The higher the Delta E, the greater the difference between the two ...

delta It is shown in capital form with the symbol of an isosceles triangle (δ) and in lower-case form with a circle with a tail on the top (δ). An example of delta being used is the use of the capital delta symbol (δ) in math equations to show a change of any quantity. For example: δ = b² - 4ac.

In chemistry, what do the delta symbols Î and Î´ stand for? Δ means the change in, and δ means a small amount of. Delta is the fourth letter in the Greek alphabet. The capital letter Δ corresponds to the English letter D, and the lowercase δ corresponds to the English letter d. In chemistry, Δ means the change in. Thus, #ΔT# means the change in #T#, #ΔE# means the change in #E#, and so on.

What does r stand for in this physics formula? So delta ( r) is the change in position as measured in the direction of the force. Often r is used as name for a position vector. It is short for radius, but it does not necessarily mean that there are any circles involved. It simply means it describes an arrow from the origin of the coordinate system to a position. delta r, then, will be a displacement vector, which will not be thought of as starting at the origin. if it's high school physics.
