Trigonometry: Graphs
Sigh... my turn to post. This is going to be about the whole graphing thing. Try not to get lost even though there's a good chance that you will.As you look and examine the images, you will see that there is some kind of pattern.
You don't have to do sine for every single degree. Once you know all the angles in one quadrant, you can find any other angle in any other quadrant.
NOTE: Sine always the 'y' value.
Unit Circles
This helps you find the related angle.
Cosine will always give and 'x' value and sine will always give you a 'y' value.
eg. cos 30 degrees = 0.886 = the 'x' value
sin 30 degrees = 0.5 = the 'y' value
NOTES: The maximum value of a unit circle is 1 and the minimum is -1.
Every time you go around the circle, it's called a "period".
Okay, this was a bad post and you know it. Once I started to do my post, I didn't really know what I was doing and that's not a good thing. SO... when I understand it better, i'll come back and edit this, tomorrow possibly.
ANYWAYS... this part is the part that most people care about. Who's going to be the next scriber? JOSEPH... isn't the next scriber. Nelsa is! =D Have fun!
