1. scientific notation - WebAssign uses scientific notation like that used in calculators. Some examples:
|number||scientific notation||WebAssign Notation|
Exponents - You may be asked to enter variabls with exponents. For example, L2. The way to enter this into your answer is as follows:
3. precision -Unless the problems states otherwise, WebAssign will allow a 2% tolorance in your answers.
4. angles - WebAssign measures angles from the positive x-axis.
Going counterclockwise from the +x-axis use values from 0 to +1800 (positive values).
Going clockwise from the +x-axis use values from 0 to -1800 (negative values).
The figure below shows an example. There area 4 vectors. The angles of these vectors, according to WebAssign, would be referenced to the +x axis. WebAssign would say the vectors are located at the following angles:
|Vector A is located at angle +30o from the +x axis
Vector B is located at angle +150o from the +x axis
Vector C is located at angle -150o from the +x axis
Vector D is located at angle -30o from the +x axis
