Numbers are commutative, since xy = y x and x y = y x for all real numbers x and y However the operation of subtraction is not commutative, since x y 6=y x in general (Indeed the identity x y = y x holds only when x = y) 33 Associative Binary Operations Let be a binary operation on a set A Given any three elements x, y andFor example, the polynomial identity (x 2 y 2) 2 = (x 2 – y 2) 2 (2xy) 2 can be used to generate Pythagorean triples Suggested Learning Targets Understand that polynomial identities include but are not limited to the product of the sum and difference of two terms, the difference of two squares, the sum and difference of two cubes, theExample 3 Identity Property 6 0 = 6 x 0 = x (a b) 0 = a b Example 4 Additive Inverse Property 3 (3) = 0 x (x) = 0 If x = y, then y = x 3 If x = y and y = 7, then x = 7 4 6 2 = 2 6 5 5 ∙ 2 = 2 ∙ 5 6 10 (3 2) = (10 3) 2 7 6(3 ∙ 5) = (6 ∙ 3)5

These identities are useful whenever expressions involving trigonometric functions need to be simplified An important application is the integration of nontrigonometric functions a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identityTherefore, x = 50 and y = 3 I dont get this at all?In the system of mathematics, the identity is always an equation which is an equilibrium relation X= Y and Y = X, X and Y are the variables and X and Y provides the similar value as each other despite whatever values they are (most probable numbers) are replaced for the variables Read about the types of Additive and Multiplicative Identity at Vedantucom
411 Hyperbolic Functions The hyperbolic functions appear with some frequency in applications, and are quite similar in many respects to the trigonometric functions This is a bit surprising given our initial definitions Definition 4111 The hyperbolic cosine is the function cosh x = e x e − x 2, and the hyperbolic sine is theIn the LHS of the identity,we put x=2&y=3 Similarly in the RHS of the identity,we put x=2&y=3 Thus, the identity is verified Now, let's expand the second Identity If we replace ywith (−y)the expression changes to (x−y)3 So to find the expansion of (x−y)3, we can replace ywith (−y)in (xy)3=x23x2y3xy2y3Get stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us!
