The distance between the points (m,-n) and (-m,n) is
(A) `sqrt(m^2 + n^2)`
(B) m+n
(C) 2`sqrt(m^2+n^2)`
(D) `sqrt(2m^2 +2n^2)`

Find the value of m and n : if : ( 3+ sqrt2 )/( 3- sqrt2) = m + n sqrt2

If tantheta+sintheta=m and tantheta-sintheta=n , then the value of m^2-n^2 is equal to (a)4 mn (b) 2sqrt(mn) (c) 4sqrt(mn) (d) 2sqrt(m//n)

sqrt(m^(2)n^(2))times root(6)(m^(2)n^(2))times root(3)(m^(2)n^(2))

If tan theta+sin theta=m and tan theta-sin theta=n , then (a) m^2-n^2=4m n (b) m^2+n^2=4m n (c) m^2-n^2=m^2+n^2 (d) m^2-n^2=4sqrt(m n)

If m = 9 and n = (1)/(3)m , then sqrt((m)^(2) - (n)^(2) = ?)

The ratio of the A.M. and G.M. of two positive numbers a and b, is m : n. Show that a : b = (m+sqrt(m^2-n^2)):(m-sqrt(m^2-n^2)) .

Find the value of m and n : if : ( 5+ 2sqrt3)/( 7+ 4sqrt3) = m + n sqrt3

The ratio of the.A.M. and G.M. of two positive numbers a and b is m : n. Show that a: b = (m + sqrt(m^(2)-n^(2))): (m- sqrt(m^(2)-n^(2)))

If A.M. and G.M. between two numbers is in the ratio m : n then prove that the numbers are in the ratio (m+sqrt(m^2-n^2)):(m-sqrt(m^2-n^2))dot

If A.M. and G.M. between two numbers is in the ratio m : n then prove that the numbers are in the ratio (m+sqrt(m^2-n^2)):(m-sqrt(m^2-n^2))dot
