## Homework Statement

The equation for the velocity of a falling parachutist can be computed by,

[tex]v(t) = \frac{gm}{c}(1-e^{-(\frac{c}{m})t})[/tex]

Use a first-order error analysis to estimate the error of v at t = 6, if g = 9.8 and m = 9.8, c = 12.5 plus or minus 1.5.

## Homework Equations

## The Attempt at a Solution

I've never done "first order error analysis" using taylor series so I've looked at the solution to try and do the problem backwards but I can't make sense of what's going on.

**(See figure attached)**

Can someone clarify to me what they're doing here? I need the ideas behind what's being done.

Thanks again!
