PrairieLearn and CBTF tips:
- Error tolerance is $1\%$. This (roughly) corresponds to using three 3 significant figures
- Do not use fractions as your input answer. Instead use decimal numbers (e.g. 2/3 is not accepted as a correct answer, however 0.667 is)
- The CBTF desktop calculator and Mathematica use radians instead of degrees for angle calculation. If you want to evaluate the cosine of a $30^o$ angle, you should evaluate $\cos[30 \frac{\pi}{180}]$
- Formula sheet available during quizzes at CBTF
