24 maj 2016 · Using mathjax, you can use the "pipe" symbol |to indicate absolute values. Try this: $$ |-3| $$ In your case: $$MAPE = \frac{1}{n} \sum_{d_i} (\frac{1}{q} \sum_{t_j} |\frac{gap_{i,j}-s_{i,j}}{gap_{i,j}}| )$$ This gives:
On many graphing utilities, spreadsheets, and CAS, the absolute– value function is denoted abs. For example, abs(x–3) = |x–3|. Example 1 Solve for x: |x - 4| = 8.1. Solution Use the algebraic defi nition of absolute value. Either x - 4 = 8.1 or x - = –8.1. So, x = 12.1 or x = –4.1. Check Use a CAS. QY1 Mental Math A company makes $6
The table summarizes the steps for solving absolute-value equations. SPECIAL CASES: Not all absolute-value equations have two solutions. If the absolute-value expression equals 0, there is one solution. If an equation states that an absolute-value is negative, there are no solutions.
