Question
At what point the tangent to the curve √x + √y = √a is perpendicular to the x-axis-
Options
A.(0, 0)
B.(a, a)
C.(a, 0)
D.(0, a)
Solution
at what point
√x + √y = √a
Let point (x1, y1)
if tangent ⊥ to x-axis the all
∴ x = 0, y = a
x1 = 0
y1 = a
point (0, a)
√x + √y = √a
Let point (x1, y1)
if tangent ⊥ to x-axis the all
∴ x = 0, y = a
x1 = 0
y1 = a
point (0, a)
