1. What i remember about transfermations is that when there is a number in the perenticies it ditermianes whether it goes up or down. And if the number is not in the perenticies it tell it if it goes left or right. If its negative it goes right on the x axis and if its positive it goes left on the x axis. i dont really have tips on how to remember how to shift but all i can think is negative is down and positive is up.
2. What i remember from trig is all the sin and cos. that cos is always x and sin is always y.
this is ditermained by the pie on the unit circle. i dont remember much about trig.
Well what i have for tips is on the unit circle is on the pie from the top to bottom right it goes pie/2 ,pie/3,pie/4,pie/6. it goes form low to high 2,3,4,6.
3. the things that worry is the sin and cos and tan. Also in how to find the inverse to something i get stuck when the y is on the bottom.
grrrr.....
ReplyDeletei feeel the same way about your worries lets help eachother out friend(:
On that last note, if you're solving for y and it ends up at the bottom of a fraction? (I think that's what you're asking)... then multiply both sides by y and then divide both sides to get the y alone.
ReplyDeletebtw, if the number is added or subtracted inside the parenthesis, then you move it LEFT/RIGHT, not up/down.
