Radii of A and that of X and Y have been given as A = 1.00 pm X = 1.00 pm Y = 2.00 pm Thus ratio of volume of AX and AY unit cells is

I fcos ^ (- 1) x / a + cos ^ (- 1) y / b = (5pi) / 12andsin ^ (- 1) x / a-sin ^ (- 1) y / b = pi / 12t hen ( x ^ 2) / (a ^ 2) + (y ^ 2) / (b ^ 2) = 1) 12) 1 & sol43) 3 & sol4

If y=1+2sin x+3cos^(2)x, find the maximum and minimum values of y AA x in R

If sin x + sin y + sin z = 0 and cos x + cos y + cos z = 0 then prove that cot (x+y)/2 = cot z and cos (x-y)/2 = pm 1/2

Statement - 1 : Equations (2 pm sqrt3) x - y = 1 pm 2sqrt3 represent two sides of an equilateral triangle having one vertex (2 , 3) and x + y - 2 = 0 as the opposite side . Statement - 2 : The equation of the lines passing through (x_(1) , y_(1)) and making constant angle alpha with the line y = mx + c are given by y - y_(1) = (m pm tan alpha)/( 1 pm tan alpha) ( x - x_(1))

Let f be a polynominal such that f(x) f(y) + 2 = f(x) + f(y) + f(xy) AA xx, y in R (0) and f(x) is one one AA xx in R with f(0) = 1 and f (1) = 2 The function y = f(x) is given by

Solve : (3)/(x + y ) + ( 2)/(x - y ) = 2 and (9)/(x + y ) - ( 4)/(x - y) = 1 .

Consider the inequation x^(2) + x + a - 9 lt 0 The value of the parameter a so that the given inequaiton is ture AA x in (-1,3)

Statement-1 : If f : [-3, 3] rarr R is defined as f(x) = [(x^(2))/(a)] , then f(x) = 0, AA x in D_(f) , iff a in (9, oo) . ([x] denotes the greatest integer function) and Statement - 2: [x] = 0, AA 0 le x lt 1 .

Radii of A^(+) and that of X^(-) and Y^(-) have been given as A^(+)=1.00 pm X^(-)=1.00 pm Y^(-)=2.00 pm Assign structure of AX and AY crystals and also determine the volume of unit cells of AX and AY crystals.
