Tips and Hints...??? {:[

1.TRANSFORMATIONS
hmmm welll.... where err.... how to start..... *sigh* nomnom (great now i have to think).
well from what i know about transformations is that if X is being added or subtracted by a number it will shift. The shift depends on whether the number is put into the INPUT or the OUTPUT. An example of a number put into the input is (x+6), this will cause th graph to shift 6 units to the left...i think.
If the number is taken and put into the output EX. y=x+6 the graph will shift 6 units up.

2.Trig.
Oh great this is about Unit Circle... me no like the unit circle. But, the main concern is memorizing all those radians and points... I don't really know how i memorize all that info. but i know that whenever the radian has a denominator of 3 the points are (1/2,3^1/2) , negative or positive depending on where it is ont the unit circle. so, that helps me know when the radian has a denominator of 6 The y=361/2 and x=1/2. when the denominator is 4 both x and y equal 2^1/2/2.

3.My worries
well idk... i guess its remembering cos, sin, tan, cotan, csc, sec and there inverse's domain and range.... yup...

Even and Odd Functions :D

Hmmmmmm... well an even function is a function thats symmetrical on theY-Axis. The input of an even function be it negative f(-X) or positive f(X) will always have the same output. So f(x) = f(-x). Even functions are symmetrical on quadrant 1 and 2 or quadrant 3 and 4.




Example of an even function: Parabola







Odd functions are functions that are symmetrical on the origin. For odd functions the input will come out opposite. this is defined as f(-x) = -f(x). Odd functions are symmetrical on quadrant 1 and 3 or quadrant 2 and 4.

Example of an Odd function: Sin X

"About Me"...

Well, my name is Melvin. I love animals and my dream job is to become a Vet. I've had a variety of pets throughout my lifetime. Hmmm...what else... oh, i also like to draw, though I'm not very good at it >__<. sometimes i don't understand myself or why I do certain things... soooo yeeaahh... i don't know if this is revelant to the assignment but i have an annoying little brother who loves to bug the s**** out of my little sister.
