TIPS AND HINTS

Tips and Hints!

1. How i remember transformation??

what i remember is that what ever is done to "x" (the input) is the other way around. and since its been added or subtracted to the x it moves along the x axis. say you add 4 to x... your graph shifts 4 units left. and say you subtract 4 to x.. your graph moves 4 units to the right.

but when things are added or subtracted from the output.. add means up. subtract means down.

for example.. f(x)= sin (x+π) -2. the graph shifts π to left and moves down 2 units.

2.hmmmm trigonometry is pretty broad.. well i'd say as long as you remember the measurements of the circle then its fine. really.. all the are are just rations. fractions.. whatever. at 30 degrees.. its π/6 simply because 60 degrees is 1/6 of 360. graphing is simple.

example: since we know that sin 0= 0, at x=0, y=0

and sin 90 degrees= 1. then just graph it and the transformation should be simple.

3. what worries me: graphing log takes time for me to do but i understand it now. all i have to do is know my graphs well. again graphing log is still my main concern. and solving log. but i don't think thats considered trigonometry. does it??????

My main advice: study your cards!!!!!!!!
