graph of the six trigonometric functions

last night im studying math133,
as preparation for my final :)

what i learned is graph of the six trigonometric functions !
1st thought is difficult
but after i learned it's same as phy143 (wave)
in this topic i learned how to;

1. Find the amplitude
2. Determine the domain
3. Determine the range
4. Determine the period
5. Differences between sin graph and cos graph
6. Draw the graph
7. State 5 key points.

for this topic i must memorize the formula
y= a sin b ( x - h)

this chapter is easier than i thought
im so into it

yeah
math ROCK
