n(A-B) + n(A intersection B) = n(A) = 14+x +x n(B-A) + n( A intersection B) = n(B) = 3x + x But n(A) = n(B) hence x = 7

The equation of the ellipse which passes through the point (4,1) and having it's foci at (+-3,0)... Chapter - Ellipse

Posted by Pratik Mishra 7 years, 10 months ago

CBSE > Class 11 > Mathematics

Chandrashekhar Wankhede 7 years, 10 months ago

In ellipse, sum of distances from a point on ellipse to foci = constant = 2a, use distance formula to find this sum of distances from point (4,1) to foci (+-3,0) and find 'a' value and then sqr(a) value. As foci are (+-3,0) , hence c = 3 . In ellipse sqr(b) + sqr(c) = sqr(a), from this eqn find sqr(b) value. Finally eqn of ellipse can be found by using sqr(x)/sqr(a) + sqr(y)/sqr(b) = 1

Chandrashekhar Wankhede 7 years, 10 months ago

Complex number can be represented as directed line from origin to a point in Argand plane which is similar to XY plane. Real part of complex number is potted on x axis and imaginary part on y axis. The length of directed line is equal to modulus of complex number where as angle made by directed line with x axis is called argument of complex number. If directed line lies in second quadrant means complex number lies in second quadrant.. In this way we can determine the quadrant of complex number..
