Platform: iOS, Android

Features
Mathfuns
is a nice compact app for the iOS and Andriod app. Features include:
Access
to the Help Screen
Assign
values, matrices, and vectors
Matrices:
LU and QR factoring, inverse, and determinant
Factor
and expand algebraic expressions
Derivatives
Integrals:
Indefinite and definite
Gamma
and zeta functions
Differential
equations (ordinary and partial)
2D
and 3D graphing
How
to operate: enter the expression.
To
calculate, press the calculator icon.
To
graph the equation, press the graph icon.
The graphs available are 2D, 3D, and a pie chart. Pie charts require lists or matrices. I have a hard time getting a pie chart to
generate.
Suggestions
Getting
around the expressions can be pretty tricky.
To input powers, call up the x^y template, then proceed. The parenthesis has a template. Only the latest expression enter can be
evaluated or graphed. When the expression
has be evaluated, a new line is not automatically connected. You must manually start a new line (by the <-|
return key).
Graphing
expressions currently only allows for positive graphing parameters, leaving graphs
to the first quadrant available. I
suggested that is addressed.
Final Verdict
I
rate the app 4 out of 5 starts and do recommend it, more for the handling of
CAS expressions. The graphing feature
needs improvement.
