# FIND THE EQUATION OF TANGENT AND NORMAL TO CURVE PRACTICE WORKSHEET

Find Equation of Tangent and Normal to Curve Practice Worksheet :

Here we are going to see some practice questions to find equations of tangent and normal to the curve.

## Find Equation of Tangent and Normal to Curve Practice Worksheet - Practice questions

(1)  Find the equations of the two tangents that can be drawn from (5, 2) to the ellipse 2x2 + 7y2 = 14.   Solution

(2)  Find the equations of tangents to the hyperbola (x2/16) - (y2/64)  =  1 which is parallel to 10x - 3y + 9  =  0.   Solution

(3)  Show that the line x − y + 4 = 0 is a tangent to the ellipse x2+ 3y2 = 12 . Also find the coordinates of the point of contact.          Solution

(4)  Find the equation of the tangent to the parabola y2 = 16x perpendicular to 2x + 2y + 3 = 0.  Solution

(5)  Find the equation of the tangent at t = 2 to the parabola y2= 8x . (Hint: use parametric form)    Solution

(6)  Find the equations of the tangent and normal to hyperbola 12x2 − 9y2 = 108 at θ  =  π/3 . (Hint : use parametric form)   Solution

(7)  Prove that the point of intersection of the tangents at ‘ t1 ’ and ‘ t2 ’on the parabola y2 = 4ax is a t1 t2 , a(t1 + t2)     Solution

(8)  If the normal at the point ‘ t1 ’ on the parabola y2 = 4ax meets the parabola again at the point ‘ t2 ’, then prove that t2  =  -(t1 + 2/t1)       Solution
