Question 1

UMS solves rational equations, which is a relatively simple task. Indeed, they can all be solved by essentially one method. What novelty does UMS bring to this task?

Answer

Question 2

How can I enter the simultaneous equations?

Answer

Question 3

I attempted to simplfy the problem (a+b)² by using the "Expressions simplification" section and got the same expression as the result. Why?

Answer

Question 4

I entered the problem fx = x² - x³ and wanted to graph the function, but UMS thinks this is an equation and solves for the equation with parameters. Why?

Answer

Question 5

I selected the "Factoring" section and entered the problem x⁴-y⁴ and got (x²-y²)(x²+y²) as a result. But (x²-y²) can be decomposed into factors (x-y)(x+y). Why didn’t UMS finish the job?

Answer

Question 6

I entered the problem 58972356356x³+23489755x⁷=357, and UMS did not solve it. Why?

Answer

Question 7

I want to use UMS to solve a problem such as: Find all values of parameter a so that both roots of the quadratic equation x²- 6ax + (2-2a+9a²)=0 are greater than 3.

Answer

Question 8

I entered the problem log(x) + log(x)² + log(x)⁴ = 7, and UMS did not solve it. Why? This seems to be a simple equation.

Answer

Question 9

I want to use UMS to find P(x) = x² - 60x +76 for x=45. I entered P(45) = x² - 60x +76, but UMS did not solve it. Why didn’t UMS find P(45)?

Answer

Question 10

I want to use UMS to find sin of 210 degrees. I entered sin(210), but UMS did not solve it. UMS Calculator gives the wrong answer! Why?
