I am already very bad at math when it comes to hw and sometimes understanding the equations. How can I understand it better or at least memorize the equation formulas for the test? What is your method? Or is it the only way to just read the equation over and over and memorize it? I know that is a bad way...but I am not born for math....the harder stuff anyways!!!

I'm working on polar coordinates and I would like to know how to approach this problem. Please do not solve for me since I do not wish to know the answer anyway. Here is the problem for reference:

To the nearest integer, what is the distance between the points of intersection of the polar curves:

r = 4cos(theta) and r = 2 / [cos(theta) + sin(theta)]

Should I convert to x and y form first? And then I don't understand what the distance between the points of interesection means here...should there even be a distance between the "Points of intersection"?

Also, this is to be done without a graphing calculator or utility.

This is ALL of the information that is given to the question.

In some codes, letters are switched with other letters. One way to break this kind of code is to examine the frequencies of the letters used in everyday language and then to compare these frequencies with the frequencies of letters used in the coded message.
The location of the letters in a word can also help you to decide which letters are vowels.
