CalcMe exercises solutions

Define the variable y as the quotient of 39 divided by 7 and the variable z as the remainder of 63 divided by 11.

Specify the variable y as a prime number and factor the variable z.

Define p as a 2nd degree polynomial in x with roots y and z.

Evaluate p in 0 and -3 and save the results in two variables, then find the greater common divisor of these results.

Illustrate the graph of p and cos(y·x+z).

Define a list L of 4 random numbers between –10 and 10, excluding 0.

Find the least common multiple of two different random numbers of the list.

Define a random number x as a decimal number (to the second decimal place) between 7 and 15 that is not an integer number.

Define a random number y as a rational number (to the first decimal place) between 3.2 and 6.8 that is not an integer number.

Define a list L of random coefficients between -5 and 5, excluding 0 of random length between 5 and 10 (creating a user function for the randomness).

Define a polynomial p(x) of degree 2 with random coefficients from the list L and find its roots.

Plot the graph of p(x) in green, draw the minimum or maximum of the function and write the point coordinates on the plotter.

Create a list K whose elements are the quotient of L's elements and its position if, and only if, its greatest common denominator is 1.
