An approximation is an estimate or close value that is not exact but provides a reasonable representation of something. It involves finding values that are close enough to be useful while acknowledging some degree of error.
An error bound refers to an upper limit on how much an approximation can deviate from its exact value.
Rounding: Rounding involves approximating numbers by replacing them with simpler or more convenient values while considering their place value.
Taylor Series Expansion: A method used to approximate functions by representing them as infinite sums of terms involving powers of variables.
