App Review: Mathfuns
Author: Guoyong Zhao
Version Reviewed: 1.1.2, 2/24/2017
Type: Graphing, CAS, Scientific
Platform: iOS, Android
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
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.
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.
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.
