Unit Circles!

<p>Hello. For all of you who took Pre-Cal...does it get easier after all of this unit circle stuff? I don't want to complain...but this is not very easy for me. :(</p>

<p>Was this especially hard in Pre-Cal, or does it get a lot worse?</p>

<p>Thanks :D</p>

<p>no .</p>

<p>the unit circle is your best friend. memorize all of the values (in radians) and you will be grateful later on. Source? I learned from my mistakes when I couldn’t remember any values, thus resulting in my <em>shock</em> C+ pre-cal final. luckily it hardly affected my grade</p>

<p>and make sure you know sin=y values; cos=x
tan=y/x.
you’ll get what i mean later on</p>

<p>Thanks! :smiley: So Pre-Cal doesn’t get much tougher than this?</p>

<p>it can be confusing with all the sins, cosines, tangents, secants, cosecants, cotangents since there’s a bunch of formulas and rules you need to know and learn(like sin^2+cos^2=1),but if you’re good with remembering formulas and such, its pretty easy.</p>

<p>Oh, I just learned that formula today! Haha. I am really giong to have to study for this upcoming test. Thanks for the replies.</p>

<p>funny cause sin^2 + cos^2 = 1 is the only one you really ever need</p>

<p>It gets easier once you grasp the unit circle concept…although I have never memorize the unit circle, choosing instead to apply the ‘special right triangles’ concept (which I thought was the same thing).</p>

<p>Good luck on your Pre-Cal class. ;D</p>

<p>

<p>It is the same thing, just in a different context.</p>

<p>pre calc is weird i will admit that
but once you take physics it all gets really natural</p>
