Question

Circular errors are caused by adding the cell name of a/an cell to a formula.

a. True
b. False

Answer 1

It is true that a vector can form the shape of a right-angle triangle with its x and y components, and true that the Pythagorean theorem can be used to calculate the length of the resultant vector obtained from the addition of two perpendicular vectors.

Step-by-step explanation:

True or False - A vector can form the shape of a right angle triangle with its x and y components. The statement is true. Any vector can be resolved into two perpendicular components, usually along the x and y axes. These components act like the sides of a right-angle triangle, with the vector itself representing the hypotenuse.

True or False - We can use Pythagorean theorem to calculate the length of the resultant vector obtained from the addition of two vectors which are at right angles to each other. This statement is also true. When two vectors are at right angles, their magnitudes act as the legs of a right triangle, and the resultant vector acts as the hypotenuse. Thus, to find the magnitude of the resultant, we apply the Pythagorean theorem.

Answer 2

Circular errors arise from self-referencing loops in formulas, not from including cell names. Adding cell names is a common practice in spreadsheet calculations, and Excel handles it without causing circular errors. So the correct option is b. False

Step-by-step explanation:

Circular errors are not caused by adding the cell name of a cell to a formula. In spreadsheet programs like Microsoft Excel, circular references occur when a formula directly or indirectly refers to its own cell. This can create a loop where the cell depends on its own value, leading to inaccurate calculations. However, simply adding the cell name to a formula does not inherently cause a circular error.

Circular errors are a result of a self-referencing loop in the calculation chain. For instance, if cell A1 contains a formula that refers to A1 itself, Excel identifies this as a circular reference. The program attempts to prevent such situations to maintain the integrity of calculations. It's crucial to understand that adding a cell name to a formula is a common and legitimate practice when building complex calculations in spreadsheets. Excel allows this and handles it appropriately without causing circular errors.

In summary, the statement that circular errors are caused by adding the cell name of a cell to a formula is false. Circular errors arise when a cell formula creates a self-referencing loop, and merely referencing a cell in a formula does not inherently lead to such errors. It's essential for users to be aware of circular references and manage them appropriately to ensure accurate and reliable spreadsheet calculations.
