Mathcad Operation tips: formula input, variable definition and calculation

Formula Input Tips:

1. Multiply the number with the symbol, you do not have to enter the multiplication sign manually ("*").

2. The following help visualize the calculation: a. Use the Math toolbar to enter and use the TAB key appropriately; B. Reasonable use of the space bar.

3. When you enter the open root, you can use the shortcut key "\" key, enter the absolute value symbol, the shortcut key can be shift+\.

4. When the cursor is on a calculation, select the Format menu->result to select the display form of the result, such as fractional, scientific notation, specified scale, and so on.

5. The "=" number solves the equation, and the cursor can be entered in any position of the calculation.

6. The base of log for 10,ln is E.

7. Variables that require user input can be set to yellow for the relevant calculation background, helping to document readability.

8. The Insert key allows you to switch the cursor from one side of the calculation to the other, making it easier to add content before or after the calculation.

Variable definition and calculation tips:

1. Initialize the value of the variable with the ":" Key.

2. Variables can be carried in units.

3. Variable names are case-sensitive.

4. Variable names should be avoided as far as possible with the name of the unit, such as "M (m)", "A (AMP)" and so on, to prevent confusion.

5. Variable names are supported with angle labels, using "." Key input, the corner mark can be a number or a letter. For example:

6. When initializing range variable, if the data interval is 1, you can enter it with "range variable" under vector and Matrix toolbar, or press ";" Key input. For example:

If the data interval is not 1, the data interval is specified by the second data in the input sequence. For example:

Supports simultaneous input of units such as:

7. When the variable is calculated, the result is solved with "=", and the result is automatically updated (unless auto-calculation is canceled in the Tools menu->calculate). For example:
