Question

What is delta? Give an example.

Answer 1

as in geography i think you are meaning a river delta (if not i’m sorry)

a river delta is often shaped as a triangle and is at the part of the river where the water dispenses into the body of water.

if you want a more composed answer here is a google definition:

A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

Answer 2

Answer:Delta is the ratio that compares the change in the price of an asset, usually marketable securities, to the corresponding change in the price of its derivative. For example, if a stock option has a delta value of 0.65, this means that if the underlying stock increases in price by $1 per share, the option on it will rise by $0.65 per share, all else being equal, Examples of Delta. Let's assume there is a publicly-traded corporation called BigCorp. Shares of its stock are bought and sold on a stock exchange, and there are put options and call options traded for those shares. The delta for the call option on BigCorp shares is .35.
