Earth rotates on an axis through its poles. The distance from the axis to a location on Earth 40 degrees north latitude is about 3033.5 miles. Therefore, a location on Earth at 40 degrees north latitude is spinning on a circle of radius 3033.5 miles. Compute the linear speed on the surfuce of Earth at 40 degrees north latitude.

You're measuring the velocity of an object by measuring that it takes $1$ second to travel $1.2$ meters. The measurement error is $001$ meters in distance and the error in time is $01$ second.
What is the absolute value of the error in the linear approximation for the velocity?

The majority of college students that seek linear approximation practice problems with answers do not really know the concept of linear approximation when using basic differential equations. The trick is to use an approximation of a general function by turning to an affine function. When you need to work with an approximation for analytical work, focus on the solutions that provide linear approximation questions and answers where you see certain relations. It is good to compare several similar answers as it may help you come up with calculations and the explanation of your approximates with the graphs and the formulas.
