0 votes 1 answer the radius of the circle is √2 Join radii to the points where the line y=1 cuts the circle from the origin to the line along the yaxis is 1, the radius is √2, so the other side of the triangle must be 1 so you have a 45, 45 90 triangle, so is the other one Both of them make a 90º at the centre the area of those two triangles is 1/2A lamina occupies the region inside the circle x 2 y 2 = 2 y but outside the circle x 2 y 2 = 1 Find the center of mass if the density at any point is inversely proportional to its distance from the origin close Start your trial now!
One variable Frequently the term linear equation refers implicitly to the case of just one variable In this case, the equation can be put in the form =, and it has a unique solution = in the general case where a ≠ 0In this case, the name unknown is sensibly given to the variable x If a = 0, there are two casesEither b equals also 0, and every number is a solutionThis video explains how to derive the area formula for a circle using integrationhttp//mathispower4ucom The locus of the centres of the circles, which touch the circle, x^2 y^2 = 1 externally, also touch the yaxis and lie in the first quadrant, is asked in Mathematics by Jagan (211k points) jee mains 19;

Pythagoras Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides x 2 y 2 = 1 2 But 1 2 is just 1, so x 2 y 2 = 1 (the equation of the unit circle) Also, since x=cos and y=sin, we get (cos(θ)) 2 (sin(θ)) 2 = 1 a useful "identity" Important Angles 30°, 45° and 60° You should try to rememberYou want the upper half of the circle only, so you want y = sqrt(10x^2)) You will reject y = sqrt(10x^2) because that would give you the bottom half of the circle which you don't wantYour domain is determined by sqrt(10x^2)) Your domain has to result in real values of yGraph x^2y^2=1 x2 y2 = 1 x 2 y 2 = 1 This is the form of a circle Use this form to determine the center and radius of the circle (x−h)2 (y−k)2 = r2 ( x h) 2 ( y k) 2 = r 2 Match the values in this circle to those of the standard form The variable r r represents the radius of the circle, h h represents the xoffset from the
