<p>I'm fairly proficient at using the calculator, but while i was using it last the past couple of days for math 2 practice tests, the calculator would give me answers i couldn't use.</p>
<p>For example:</p>
<p>input: (sin (x))/(cos (x)) output: (sin (x))/(cos (x))</p>
<p>input: ln (5) output: ln (5)</p>
<p>Can someone help me configure the calculator for the math 2 subject test? Thanks in advance!</p>
<p>What type of calculator do you have? If it’s the TI-Nspire CAS, I can definitely help, but I’m not very proficient with other calculators.</p>
<p>If you have an N-Spire, there’s an option that allows you to change between “Auto” and “Approximate.” The “auto” gives you the exact form, i.e. if you type in “10/45” it’ll just return “2/9” instead of “0.222…” I think you can also do that on a TI-84.</p>
<p>Also, on the N-Spire, Ctrl+Enter works for approximation.</p>
<p>Or, just putting a decimal point at the end. For example, if “10/45” returns “2/9,” then “10/45.” should return “0.222…”</p>
