How can I type the interval −10 ≤ x=>10

The function y= log((x+sqrt(x.^2)+1));

a. Evaluate the values of function between the interval −10 ≤ x=>10

Setp size of 0.1

Answer 1

[Walter Roberson]

The interval defined by -10 <= x >= 10 in steps of 0.1 is

x = 10 : 0.1 : inf;

because all values that are greater than or equal to 10 are also greater than or equal to -10

However, in practice the numbers that can be represented get further apart than 0.1 after 562949953421312 so you should use

x = 10 : 0.1 : 562949953421312

Good luck having enough memory to solve the question.
