<p>Hi, I’m a math major, and I lack understandings on basic graphs and trigonomitry. So, I am thinking of taking “Algebra and Calculus” (class that can be taken before calcI) which is mostly based on trigonometry and graphs of exponential and logarithmics. Is it a bad idea? </p>
<p>P.S. I am finishing up CalcIII this semester.</p>
<p>Whoa. That is pretty extraordinary. Though quite impressive too!</p>
<p>I would actually advise against taking the class, if only because trig and graphs are very easy to self-study. Just go to the bookstore and pick up a trig textbook, and you should be fine.</p>
<p>Good luck!</p>
<p>I would say if you are having difficult (after Calc III) of recognizing/freehand sketching graphs of functions, you might be in some trouble as a Math Major. I would not say it is a bad idea if you failed to learn it the first time around (how did you get out of Pre-Cal and Calc I?), however - aside from Differential Equations - your experience with trig is going to be limited (since you already encountered it in Calc); and certainly not graphing trig functions.</p>
<p>For your own sanity, and your ability to say “I’m a math major”, you definitely want to have a facility with these two topics you feel you have not mastered.</p>
<p>The good news is that you are mostly done with trig after Calc 3. (You might see some in differential equations or complex analysis if you choose to take them, but I’ve never had to do computational trigonometry for either.)</p>
<p>The bad news is that anything analysis-related (differential equations, real analysis, etc) is going to be a nightmare if you don’t have much intuition for graphs.</p>
<p>I would encourage you to learn pre-calc material inside out. If you don’t want to take the class for credit, you could also audit it (though you might have less motivation to do the homework).</p>
