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? AnswerQuestion 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? AnswerQuestion 4 I entered the problem fx = x^{2}  x^{3} and wanted to graph the function, but UMS thinks this is an equation and solves for the equation with parameters. Why? AnswerQuestion 5 I selected the "Factoring" section and entered the problem x^{4}y^{4} and got (x^{2}y^{2})(x^{2}+y^{2}) as a result. But (x^{2}y^{2}) can be decomposed into factors (xy)(x+y). Why didn’t UMS finish the job? AnswerQuestion 6 I entered the problem 58972356356x^{3}+23489755x^{7}=357, and UMS did not solve it. Why? AnswerQuestion 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 x^{2} 6ax + (22a+9a^{2})=0 are greater than 3. AnswerQuestion 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. AnswerQuestion 9 I want to use UMS to find P(x) = x^{2}  60x +76 for x=45. I entered P(45) = x^{2}  60x +76, but UMS did not solve it. Why didn’t UMS find P(45)? AnswerQuestion 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? Answer
