cos2 Θ + sin2 Θ = 1
cos2 Θ = 1 − sin2 Θ
a2 − b2 = (a + b)(a − b)
If x = a cosΦ + b sinΦ and y = b cosΦ + a sinΦ, then find the value of x2 + y2 is ?

Simple equations are mathematical expressions that involve one or more variables and follow the basic algebraic form. In these equations, the goal is to find the values of the variables that satisfy the given conditions. Simple equations typically consist of addition, subtraction, multiplication, and division operations, making them fundamental to understanding algebraic concepts.
