<p>My school listed precalculus as a CO-requisite, not PRE, for this AP class but apparently my teacher didn't get the notice. He expects us to know trig inside and out..and I've never seen it before..so now I just spent the past two hours trying to teach myself. Should i drop this course?? I feel like I'll bomb all the tests because I'm not familiar with the trig.. and he's a really bad teacher.</p>
<p>oh well you shouldn't worry the trig it's not really anything past what you learn in geometry like how too use sin, cos, tan and their inverses when you see triangles oh yeah and it saves you a lot of time if you know how to use the 45, 45,90 rule and the 30, 60, 90 rule. Seriously that's the hardest the trig gets for physics B and its really nothing to worry about because I didn't have pre-calc during that class and I ended up with a 4</p>
<p>Hmm. That's a tough one. For one, you don't really need to know trig inside and out for Physics B.</p>
<p>At this point, I'm guessing you're at vectors. All you really need to know for that is sohcahtoa. And those sorts of basics. Post problems you're having trouble with on here, and we'll help you.</p>
<p>I don't know whether or not you should drop though. How much trig have you had?</p>
<p>yes, we're at vectors. and I've heard that's the easiest part.....</p>
<p>Is that all the trig i'm gonna need?
I've never had trig before. I'm taking precalc concurrently but we don't get to trig till a looooong time. whereas in phyics, we just dove right in.</p>
<p>Vectors aren't necessarily the easiest part, but they're probably the most important thing to know, since almost everything else in physics will use them.</p>
<p>When I asked how much trig you've had, I didn't mean in a precal setting, but at the end of geometry, you guys never learned sin, cos, and tan? You really don't need to know that much trig for physics. You could probably learn everything you need to know in a few hours.</p>
<p>Look in the back of your physics textbook for the appendices. There's usually a math review. If there isn't go to this website.
Basic</a> Trigonometry
You should be able to hold off for quite a while if you just read section one.</p>
<p>bro...its no big deal. Just know what a triangle is.</p>
<p>If you know SOHCAHTOA you'll be fine.</p>

<p>Not everyone finds this stuff easy. Physics makes everyone feel stupid at times. At least it did for me. Don't make people feel dumber by telling them that all they need to know is what a triangle is.</p>
<p>We had our first (non-multiple choice) test recently in AP Physics B. I hadn't done well on the math/science diagnostics (I never even had Physical Science, much less honors physics), and parents were about to have me drop the class. I was very happy that I made a 100, because I didn't feel good about it at all. It seems to me that, if you stick with physics and know the basics (Trig)... it has more to do with critical thinking skills... which will increase with Physics.</p>

<p>relax budh...
I'm sorry if I hurt your feelings.
I was just trying that not much trig is required and that it's not very difficult in a humorous and metaphorical manner.</p>
<p>Some people are just too sensitive...</p>
<p>I just wish they wouldn't put seniors and juniors in the same classroom because most of the seniors already took honors physics or precalc. it definitely does make me feel stupid when the teacher rushes through stuff and I can't ask him something which is probably really obvious to everyone else.</p>

<p>Hey well, at least you don't have people asking you how you are in AP Physics, considering the fact you suck at push-ups. (Apparently some slow people actually believe in an AP PE: AP Physics)</p>
<p>Yes i understand what ur going through @ OP
(been through similar things, i dint do functions when i was in grade 10 and in my new school where i joined for gr.11 they were doing precalculus...and i was like wa? huh? excuseme? )
U can try this approach:
1-try getting wat the material for each lesson is going to be or atleast the immediately next lesson
2-just flip through the pages, see if theres any Trig going on in there.
3-learn it (maybe) if u cant reserve it for the teacher and ask him after class.
----- ^ a bit ideal. but might work</p>
<p>a more easy thing to do:
if u know Trig is ur only problem. Then just learn it from a Senior or tutor.</p>
