Unformatted text preview: We’ll need the following for our ds . The arc length formula for polar coordinates is then, where, Let’s work a quick example of this. Example 1 Determine the length of . Solution Okay, let’s just jump straight into the formula since this is a fairly simple function. We’ll need to use a trig substitution here. The arc length is then, Just as an aside before we leave this chapter. The polar equation is the equation of a spiral. Here is a quick sketch of for ....
