1. Welcome to the Pre-Calculus Flash Drill!

2. I’m going to ask you a lot of questions about math
I’m going to ask you a lot of questions about math. These are facts that you should know extremely well. You also need to be able to recall them quickly if you want to succeed in Calculus.
I will be moving quickly through the slides so have pen and paper handy to jot down your answers.
Ready?

3. Define an
Even Function

4. the graph is symmetric with respect to the y-axis

5. Define an
Odd Function

6. the graph has symmetry to the origin

7. See if you can identify the function that probably goes with each of these simple graphs….

9. How about these?

11. What about this one?

12. Did you know it?
You are a tiger!

13. How about these?

14. and
respectively

15. and finally:

17. The graph of x = a
is…

18. … a vertical line.

19. The graph of y = b
is…

20. … a horizontal line.

21. OK…that’s enough about graphs!
Let’s move on…

46. OK…enough of the logs already!

47. The formula for the slope of a line is

49. Point slope equation of a line ?

51. Midpoint Formula = ?

53. Distance Formula=?

55. Define:

56. {
x for x 0
|x|
-x for x<0

57. We know it as int(2.98)

58. (Greatest integer < 2.98)

60. You always round down the number line!

61. Here comes your favorite thing!
Yeah! Trigonometry!

87. because:

89. (or undefined)

93. or

94. What are the Principle domains of the 6 trig functions?
That is, what quadrants are the angles in which can be used to answer inverse trig function problems?

95. for cosine
for sine
for tangent
(Different texts assign different principle domains to the other three trig functions, so we won’t bother with them.)

103. sine and cosine have to be equal!

105. Answer:

106. OK…now let’s see if you know your identities!

108. I hope you knew that one!!!

110. OK, that’s really the same one!

112. That was easy!

114. Did ya get the ol’ “stamp of approval” on that one?

116. They’re laughing because this is really the same one again!

120. This one is very important!!

121. Now for a little algebra and you’ll be done!!

125. Notice there is NO “2”

127. Still no 2!!!

128. (almost finished!!!)

129. There’s that two you wanted before!!

130. Last one!!!!

131. Use the binomial Theorem.
Don’t be foiled!
Use the binomial Theorem.

132. If you know all this material, then you are prepared to begin calculus… All you need now is a sharp mind, a sharp pencil and a really big eraser!
