Question 1.1 a-d please explain solving method

Simplify the following expressions (note that dj is the Kronecker delta, repeated index
means summation).
(a) St
(b) Ssc dic
(c) SpOpt
(e) Sfr SrsXt

Expert Solution

Step 1

To solve these expressions, use the definition of the Kronecker delta, which is a mathematical object that simplifies expressions involving indices.

The delta function is equal to 1 when the two indices are the same, and 0 otherwise.

By using this property, one were able to simplify the expressions to a form that is easier to understand and work with.

In general, when simplifying expressions with indices, it is important to be familiar with the properties of the Kronecker delta and to use them appropriately.
