Question
The abscissa of the point on the curve √xy = a + x, the tangent at which cuts off equal intercepts from the co-ordinate axes is (a > 0)
Options
A.
B.
C.a√2
D.-a√2
Solution
y = 
⇒ y = 
+ 2a + x
+ 1 = - 1 (for equal intercepts)
x2 =
⇒ x = ± 
⇒ y = + 2a + x + 1 = - 1 (for equal intercepts)x2 =
⇒ x = ± Create a free account to view solution
