MATHEMATICS 1 EXCEL EXERCISE
Choose 8 equally spaced points in the interval [0, 1.3] to calculate the following:
• tan(x)
• x + x3
• The difference x + x3 − tan(x).
• The absolute value of the difference. (This is also known as the error, when we think of x + x3 as an approximation to tan(x).)
Use Excel on your iPad to perform the calculations. See the videos “Introduction to Excel on the iPad” and “Maths 1 Excel Exercise”, for help with using Excel on your iPad.
Now modify your Excel file to estimate the maximum error when x + x3 is used to approximate tan(x) for x ∈ [0, 1.3].
