Simplifying Algebraic Fractions that Contain Addition and/or Subtraction
By Jim Cihak
In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions, which contain addition and/or subtraction, to their simplest form. This activity has audio content.
The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.
