WebbIn mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1.The multiplicative inverse of a fraction a/b is b/a.For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), … Webb− = − 1 2 2 ((2 1)) 4 cos( ) 1 n n x x π Another infinite product, again going back to Euler, is that for the Riemann zeta function. It can be expressed in terms of prime numbers pn as- ∏ ∞ = − = 1) 1 (1 1 ( ) n z p n ζz A good discussion of how this result is derived can be found in the book “Prime

Webb19 sep. 2015 · color(blue)((x+6) (x-7) is the factorised form of the expression. x^2 - x-42 We can Split the Middle Term of this expression to factorise it. In this technique, if we have to factorise an expression like ax^2 + bx + c, we need to think of 2 numbers such that: N_1*N_2 = a*c = 1*(-42) = -42 and N_1 +N_2 = b = -1 After trying out a few numbers we … WebbSince a+b is positive, a and b are both positive. List all such integer pairs that give product 42. 1+42=43 2+21=23 3+14=17 6+7=13 . Calculate the sum for each pair. a=6 b=7 . The solution is the pair that gives sum 13. ...
