## Expressing a Complex Number in Trigonometric or Polar Form, Ex 3

OK, so one last example here of converting a complex number into polar form. So here we’ve got 3 minus i squared (sorry – had a little ink run up there – a little dot). So 3 minus i squared … the first thing I’m going to do here is rewrite this as something a […]

## Double Integrals in Polar Coordinates – Example 2

Welcome to a second example of converting a double integral in rectangular form to polar form. As we discussed in a previous video. To convert a double integral in rectangular form to polar form. We have to convert the function f of x, y into a function in terms of r and theta. And differential […]

## Ex: Find the Rectangular and Polar Equation of a Circle From a Graph

– WE WANT TO WRITE THE RECTANGULAR AND POLAR EQUATION FOR THE GIVEN GRAPH OF THE CIRCLE. WE’LL WRITE THE RECTANGULAR EQUATION OF THE CIRCLE USING THE STANDARD FORM OF A CIRCLE GIVEN HERE, WHERE THE CENTER OF THE CIRCLE WOULD HAVE THE COORDINATES (H,K) AND R=THE LENGTH OF THE RADIUS OF THE CIRCLE. NOTICE […]

## Complex Numbers: Convert From Polar to Complex Form, Ex 1

All right, in this video we’re going to do some examples of going from, basically, our polar form back to our complex form. So a couple examples here… And I think these are certainly a little bit easier to do than putting them into polar form because really all you have to do is just […]
