the author of this app says:
MathHelper allows you to solve math exercises and get full steps of sollution
ATTENTION: Finally! Math Helper opearates on English and German language (including built-in math reference)!!!
2.0 version is released!
MathHelper is a unique application for students. The uniqueness of the application is that it allows us to see not only the answer, but a detailed solution of the problem. Now you do not need to order the work in math or ask for help from classmates - assistant in mathematics will do everything himself. In addition to solving problems, the application includes the theory on these topics and a scientific calculator.
Indispensable application for the pupils or students of the institutes, schools, during the session, exams, tests, and just learning, it is much better than any cheat sheets!
MathHelper Lite allows you to solve a wide range of tasks.
MathHelper allows you to quickly solve typical mathematical exercises of the linear and vector algebra, devided in 4 sections:
1. Linear Algebra - Operations with matrices:
*Calculate determinant of a Matrix
*Adding and Subtracting Matrices
*Scalar Matrix multiplication
*Calculate the rank of a Matrix
2. Linear Algebra - Systems of linear equations:
*By the inverse of the matrix
3. Vector Algebra - Vectors:
*Finding the magnitude or length of a Vector
*Collinearity of two Vectors
*Orthogonality of vectors
*Vector Addition, Subtraction and Scalar Multiplication
*Finding the Angle Between two Vectors
*Finding the cosine of the angle between the vectors AB and AC
*Finding the projection of one Vector on another
*Coplanarity of the Vectors
4. Vector Algebra - Figures:
*Calculate the area of a triangle
*Whether the four points lie on one plane
*Calculate the volume of a tetrahedron (pyramid)
*Find the volume and height of a tetrahedron (pyramid)
Now it's operating in German and is extended in the following areas and tasks:
5 Probability Theory (new in v.2!):
*Finding the expected value
*Finding the sampe variance
*Finding the number of permutations of n distinct objects
*Finding The number of permutations of n objects taken k at a time
6 The number sequences (new in v.2!):
*Finding LCM and GCD
*The least common multiple and greatest common divisor
*Complex numbers: Addition, subtraction, multiplication and division
*Erection of a complex number to a power
*The arithmetic and geometric progressions: n-th term and the sum of first n terms of the progression
*Calculating the Fibonacci numbers
*Solving Diophantine equations
*Finding the value of the Euler's totient function
*Finding Factorial of n!
