Question 1
The normal to the curve x = a(cosθ + θ sinθ), y = a( sinθ - θ cosθ) at any point ‘θ’ is such that
Question 2
The normal to the curve x2 + 2xy – 3y2 = 0, at (1, 1)
Question 3
A function y = f(x) has a second order derivative f″(x) = 6(x – 1). If its graph passes through the point (2, 1) and at that point the tangent to the graph is y = 3x – 5, then the function is
Question 4
Tangent to a curve intersects the y-axis at a point P. A line perpendicular to this tangent through P passes through another point (1, 0). The differential equation of the curve is
Question 5
If m be the slope of a tangent to the curve e2y = 1 + 4x2, then -
Question 6
The number of values of c such that the straight line 3x + 4y = c touches the curve is
Question 7
All the points on the curve y = at which the tangents is || to x axis lie on
Question 8
The point of intersection of the tangents drawn to the curve x2y = 1–y at the points where it is meet by the curve xy = 1– y, is given by
