If x + 1/x = √3.then find x100 + 1/x100.what is the solution

x+1/x= √3 you consider x=cos(teeta)+i sin(teeta) then substitute teeta = 30 degrees then x 100 +1/x 100 =cos(100 teeta) by the complex number concept = cos (3000) = -1/2 thank you

x + 1/x = √3 squaring both sides, x^2 + 1/x^2 = √3 – 2 again squaring, x^4 + 1/x^4 = ( √3-2)^2 -2 . . Go on like this on series for up till x^100 + 1/x^100

Tangents from the points T to the ellipse x2-y2 equal 1 cut off a length equal to the minor axis from the tangent at (a,0). Prove that T lies on a parabola

I apologize for my mistake.it should be a standard form ellipse, that is x^2/a^2 + y^2/b^2 = 1. Hope you can give me required detailed solution for this problem

 JOEL JOHNSON 2 months ago

Dear Joel, First of all The eqn. x2-y2 equal 1 doesn't makes sense. It's not an ellipse. Check the required eqn plz.
