Steps on TI-30X IIS:

1. Ensure calculator is in "DEG" (degree) mode.
2. Enter: 5 / cos ( 60 )
3. Press ENTER.

Result: 10. The ladder is 10 feet long. The TI-30X IIS handles trigonometric functions efficiently, making it simple to solve such problems.

Example 2: Calculating Statistics for a Dataset

Problem: Find the mean and standard deviation for the following test scores: 85, 92, 78, 88, 95.

Inputs: Dataset = {85, 92, 78, 88, 95}

Steps on TI-30X IIS:

1. Press 2nd then STAT (above DATA key).
2. Select 1-VAR for one-variable statistics.
3. Enter each data point using the DATA key, pressing ENTER after each.
4. Press 2nd then STAT VAR (above VAR-DATA key).
5. Scroll through the variables (n, x̄, Sx, σx) to find the desired results.

Results:

• Number of data points (n) = 5
• Mean (x̄) = 87.6
• Sample Standard Deviation (Sx) ≈ 6.54
• Population Standard Deviation (σx) ≈ 5.86

The calculator provides these values quickly, which is invaluable for statistics courses and statistics tutorials.
