" 4.If "cosec^(2)theta=(4xy)/((x+y)^(2))" then find relation between "x" and "y

sec^(2)theta = 4xy/(x+y)^(2) is true if and only if

"sec"^(2) theta = (4xy)/((x + y)^(2)) is true if and only if-

sec^2theta=4xy/(x+y)^2 is true if and only if

Show that the equation sec^(2)theta=(4xy)/((x+y)^(2)) is only possible when x=y

Is the equation sec^(2)theta=(4xy)/((x+y)^(2)) possible for real values of x and y ?

Fill in the blanks If x cosec theta = 1 and y cot theta = 1 then the relation between x and y without theta is____.

If x = a sec theta and y = b tan theta , then find the relation between x and y free from theta .
