If `"cosec"^(2) theta = (4xy)/((x+y)^(2))`, then

"sec"^(2) theta = (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

If cosec theta=(x^2+y^2)/(x^2-y^2) , then what will be the value of tan theta ? यदि cosec theta= (x^2+y^2)/(x^2-y^2) , tan theta का मान क्या होगा ?

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

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

The equation sec ^2 theta = ( 4xy )/( ( x+y)^2) is possible for x,y, in R only if
