If `x=acostheta and y=bsintheta ` ,find the relation between x and y.

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

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

y is the sum of two variables, one of which vaaries directly with the variable x and the other varies inversetly with x, If y = -1 when x = 1 and y = 5 when x = 3, then find the relation between x and y .

A variable is the sum of two such quantities one of which varies directly with x and the other varies directly with x^2 . If y =3 when x =1 and y=10 when x=2 , then find the relation between x and y .

If x prop y^2 and y = 2a, when x = a, then find the relation between x and y.

If xprop y^(2) and y= 2a when x=a, then find the relation between x and y .

y is sum of two variables, one in which varies directly with x and another varies inversely with x. When x= 1 then y = 1 and x = 3 the y = 5. Find the relation between x and y,

If x= arcos theta cos alpha,y =br cos theta sin alpha,z = cr sin theta , then find the relation between x,y,z independent of theta,alpha .

If 1/y - 1/x prop 1/x - 1/y then find the relation between x and y.

if tan( (pi)/9),x, tan ((5pi)/18) are in A.P. and tan(pi/9), y,tan ((7pi)/18) are also in A.P. then find the relation between x and y
