How much trigonometry is involved in economics?

<p>Hello everyone. I ask this question because I took business calculus rather than taking the traditional calc class, and we didn't really deal a whole lot with trigonometry. </p>

<p>I know how to derive, integrate, and know some multivariable calculus so long as trigonometry isn't involved. Is this enough to get me through, at least at the undergrad level? Thanks!</p>

<p><em>bump</em></p>

<p>To be more specific, is trigonometry used in intermediate micro, macro, or econometrics? How about other undergrad econ classes? I know that grad level econ is more “math-y”, but at the undergrad level is it more about the main concepts than it is about the math?</p>

<p>I took those subjects at the graduate level and can’t remember once using trigonometry.</p>

<p>That’s a relief! How about game theory? Can you think of anytime you would need trigonometry in economics? Or are we mostly dealing with polynomial, logarithmic, exponential, and power functions? And thanks for the response, @geo1113 !</p>

<p>Not in game theory either. And yes, It was over 25 years ago, but I think you hit the major categories. Linear algebra was used in advance stat classes and econometrics.</p>
