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


3 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)
