                                        radius of circle=2
so length of chord=2√2
let O be origin and P be mid-point of chord
OP=sqrt(4-2)=√2
so locus is x2+y2=2

If the point (at^2 , 2at ) be exttemity of focal chord of parabola y^2 = 4ax then show length of focalchord is a(t + 1/t^2)

Find the eqn of focal chord using the condition that the focal chord passes through the focus(a,0) as well as(at^2 , 2at) by using the two point form of the straight line. Now, find the...

The equation of a straight line passing through the point (-5,4) and which cuts an intercept of root(2) units between the lines x+y+1=0 and x+y-1 is?

Hello Student. Please find the solutionx+y+1=0 and x+y-1 are two parallel lines and distance between them is mod|\frac{1-(-1)}{\sqrt{2}} |So distabce between them is 2/root2 = root2So our...

sin(270-theta)= -cos theta

As u know at the Y-axis function will change. So here sin function will convert in to cos function. Sin function is -ve int 3 rd qua. so cos function will become -ve. Like, I have sin(240)...

sin(270-theta) = -cos theta is right. Because in in unit circle 270-theta means u will in third qua. & in third qua. sin function is negative.
