Calculus 4E-Ch 8 & 9
Calculus 4E-Ch8:The Limit, Ch9:Method of Approximation&DefiningInstant.Speed
| Question | Answer |
|---|---|
| Dividing by zero gives us an ________________ value in mathematics and is considered ______________________. | undefined; forbidden |
| The LIMIT of a function is the value you approach but never ______________. | reach |
| The PARADOX of speed is that speed is clearly a _______________ reality but seems __________________ incoherent. | physical; mathematically |
| According to convention, the ____________ of the function f (x) is x and the ____________ is f(x) (or sometimes y). | input; output |
| A value is forbidden for a specific function when it makes the denominator equal to ______________. | zero |
| Write the formula equivalent of this statement: "1 is the limit of the function f(x) as x approaches 0." | ____________________________ |
| We would say x ≠ 0 beside a DERIVED/simplified function when | 0 was the forbidden x-value from the ORIGINAL formula for the function (PRIOR to it being simplified). |
| A function ________ have a limit and a value at the SAME point SIMULTANEOUSLY. | can |
| The 3 main concepts of calculus which are tied together by the Fundamental Theorem of Calculus are: | 1) the limit of a function; 2) the derivative of a function; 3) the integral of a function |
| The ___________ is the most important of the 3 concepts of calculus because the other two are defined in terms of it. | limit |
| Calculus helps us understand Western ____________________ history. | intellectual |
| The ancient problem of change asks why there is both change and ____________ in the world. | order |
| It is easy to determine the instantaneous speed of an object when the speed is ______________, but most speed is NOT constant. | constant |
| the formula for average speed | v(ave) = Δd/Δt |
| Acceleration means that speed is not constant, that speed IS _____________________. | changing |
| Using the METHOD of APPROXIMATION, we find the instantaneous speed at some particular instant by calculating the AVERAGE speed over | SMALLER and SMALLER time intervals near the particular instant. As the time interval approaches 0, the avg velocity approaches the instantaneous velocity for THAT particular instant. |
| In the METHOD of APPROXIMATION, we can make the time interval as ____________ as we want, depending on how accurate we want to be. | small |
| In the METHOD of APPROXIMATION, we calculate the average speed for multiple time intervals so that we can see | the metaphorical "path" that the average speed is taking as it approaches the instantaneous speed. |
| As Δt approaches 0, the average velocity approaches the ____________________ velocity. | instantaneous |
| Instantaneous velocity is the LIMIT of the average velocity as Δt approaches _____. | 0 |
