CAS for Android is the first computer algebra system for Android. Computer Algebra systems solve equations symbolically, meaning that rather than simply solving for a numerical value, answers can be left in terms of variables.
It can be used for classes ranging from Algebra I to Calc III.
CAS for Android currently supports:
Solving Ordinary Differential Equations
Both Definite and Indefinite Integrals (single, double, and triple)
First, Second, and Third Derivatives
First, Second, and Third Partial Derivatives with respect to multiple variables
Calculating Arc Length
Calculating Tangent Lines and Tangent Planes
Calculating Taylor Series
Isolating Variables in Equations
Solving Systems of Equations
