the area of the triangle formed by the tangent at the pt. (a,b) to the circle x2 +y2 =r2and the coordinate axis


2 years ago


Answers : (1)


Equation of tangent is 


ax+by-r^2 = 0

In x-y intercept form


x/(r^2/a) + y/(r^2/b) = 1


x-intercept = r^2/b

y-intercept = r^2/b


Area of triangle = 1/2*r^2/b*r^2/b = r4/(2ab)

If the vertices of triangles are placed at (2,2), (-2,-2), (-2 root3, 2 root3). Where is the circumcentre located? Please explain
This is an equilateral triangle wiht sides root 32. So, the centroid, circumcentre, orthocentre, incentre will coincide. and will lie inside the triangle.

Find the equation of the ellipse whose axes are of lengths 6 and 2√6 and their equations are: x-3y+3=0 and 3x+y-1=0 respectively
It's equation is ((x-3y+3)^2)/10 * 1/6 + ((3x + y - 1)^2)/10 * 1/9 = 1 Thanks and Regards, Pratik Tibrewal, askiitians faculty, BTech IITG

(*) If tan A =(x sin B )/(1-xcosB) and tan B =( y sin A) / (1-y cos A) then sin A / sin B =
tanA = xsinB/(1 – xcosB) = > cotA = (1 – xcosB)/xsinB = 1/xsinB – cotB cotA + cot B = 1/xsinB …......(1) tanB = ysinA / (1 – ycosA) => cotB = (1 – ycosA)/ysinA = 1/ysinA – cotA cotB + cotA =...
