UCR - MATH 005 - Class Notes - Week 7

Created by: Mark Notetaker Elite Notetaker

background image Precalculus - the main things that will be on this midterm is how to manipulate unit  circles and rotate them around a point and for this you just use the 
formula 
(ac-bd, ad+bc) - I expect that there will be a couple questions on graphing polynomials  with high exponents. Basically, just review the notes that he gave us in
class and a good idea would be to practice graphing the vertical 
asymptotes first and then graphing the individual lines according to 
their degree
- Since this is a cumulative midterm, the questions given to us on this  midterm will be question from the new material that we have just 
learned and from the material we have learned prior to this midterm. 
Basically, just know everything from the start of the class to this point. 
Sin, cosine and tangent functions -   You should be familiar with cosine, sine and tangent functions and  more specifically, how to calculate them given a coordinate. For 
example, If you were given (1/3,SQRT8/3) you should very easily be 
able to identify that the cos of this angle would be 1/3 and the sine of 
the angle would be SQRT8/3
-   P level question should be second nature to you if you would like to  pass the midterm at the very least. Such as converting from radians to 
degrees and degrees to radians.
-   Know how to sketch graphs of high functioning polynomials, but know  how to sketch them when inequalities are involved. To do this all you 
have to do is take the inequality such as f(x) > 0, and only graph the 
lines above the x-axis.
-   Know how to determine whether a polynomial is even, odd or neither.  To figure out whether the function is odd even or neither. Plug in -1 for 
x and if the answer is the odd version of the original function, then the 
entire function would be considered odd. And if you plug in -1 for x and
get the same exact answer as the original function, then the function 
would be even. In the case that you plugged in -1 and got different 
numbers than the original function. Then your function would be 
neither even nor odd.
