![]() Note: To calculate a function, type its code (for example, SQRT for square root), and immediately follow it with the number, angle, or variables in parentheses, as shown in the Syntax column. You can use the math and trigonometry functions in the following table for your equations. Supported math and trigonometry functions You can use the following operators in your equations. For example, Type (6+7) / (4*sqrt(3))= and then press Spacebar to calculate the answer to (6+7) divided by (4 times the square root of 3). For example, type sin(30)= and then press Spacebar. For example, type 48*$129.99= and then press Spacebar to calculate the cost of 48 monthly payments at $129.99 a payment. For example, if the total revenue per year is $215,000, type $215,000/12= and then press Spacebar. Examples of simple calculationsīelow are a few examples of mathematical expressions that OneNote can calculate. If you want only the answer in your notes, after it’s calculated, you can delete the equation that precedes it. To create a new line after the answer, press Enter (instead of Spacebar) after the equal sign. For example, SQRT(3)=, sqrt(3)= or Sqrt(3)= will calculate the same answer. Type the numbers, operators, and functions as one single, continuous string of text.įunction codes are not case-sensitive.
