OneNote is a useful application for taking quick notes in the class, meeting or conference. But there is another useful feature of OneNote, it can help do quick mathematical calculations while taking notes.
Perform Simple Calculations
Solving math problems or doing calculations is very easy in OneNote. All you have to do is write down your equation like you would in a scientific calculator (in a single string without any spaces).
Press the = sign following your expression and hit the spacebar. OneNote solves the expression and displays the result after the spacebar.
1) Type a simple expression like 52+8-20+17= and press spacebar. The result will be displayed as 57.
2) You need to find the total labor cost of a project at $150 per resource for 15 resources. You can type in an expression as 150 * 15= and press Spacebar. The result will be displayed as 2250.
Supported Mathematical Operators
OneNote supports all the basic arithmetic operators like the plus (+), minus (-), multiplication (upper & lowercase x , *), division (/), percentage (%), caret (^) for exponential, and factorial (!).
4!= will give the result as 24.
5^2= will result in 25.
Supported Math And Trigonometry Functions
OneNote also supports a host of math and trigonometry functions like ABS for calculating the absolute value of a number, LOG to return the natural logarithm of a number, TAN to return the tangent of a number and so on. Simply type the code of the function that you intend to use (like ABS, LOG, TAN, etc) followed by the number or variable in the parenthesis followed by the equal sign (=) and spacebar. The result of the function will be displayed instantly.
The log below gives the syntax to be used to perform some of these operations:
ABS Returns the absolute value of a number ABS(number)
ACOS Returns the arccosine of a number ACOS(number)
ASIN Returns the arcsine of a number ASIN(number)
ATAN Returns the arctangent of a numbe ATAN (number)
COS Returns the cosine of a number COS(number)
DEG Converts an angle (in radians) to degrees DEG(angle)
LN Returns the natural logarithm of a number LN(number)
LOG Returns the natural logarithm of a number LOG(number)
LOG2 Returns the base-2 logarithm of a number LOG2(number)
LOG10 Returns the base-10 logarithm of a number LOG10(number)
MOD Returns remainder of a division operation MOD(number)
PI Returns the value of π as a constant PI
PHI Returns the value of φ (the golden ratio) PHI
RAD Converts an angle (in degrees) to radians RAD(angle)
SIN Returns the sine of the given angle SIN(angle)
SQRT Returns a positive square root SQRT(number)
TAN Returns the tangent of a number TAN(number)
The Mathematics Ribbon
OneNote 2010 has a mathematics ribbon which further helps in doing the math. For example, the ∏ or Equation option on the ribbon lets you insert common mathematical equations or create your own equations using a library of symbols.
Similarly the Compute and Graph options let you solve, integrate or differentiate equations and numbers and create 2D and 3D graphs.
