Question

diffrence between Linear equation and identities

Answer 1

Equation means equality. They are both related to the word equal. If such an equality is true for all values of thevariable, it is called an identity, e.g., sin 2 ⁡ x + cos 2 ⁡ x = 1 is true for all x.

Answer 2

linear equations may or may not have a particular expansion series for example x^5 * x^4 *
identies are of a particular expansion series like (a+b)^2 = a²+2ab+b²
