Mathematics Formula Sheet
Non-Secure
End-of-Course Math – Spring 2013
During the mathematics testing session, students are permitted to use the following
formula sheet as a reference.
Proctors and Students:
●
This formula sheet may not be used as scratch paper.
●
Test proctors must collect and account for all mathematics formula sheets
provided during the assessment.
This page contains formulas you may find useful as you work the test questions.
Use at least two decimal place values when approximating square roots or
trigonometric ratios.
