Question

In equation of tangent and normal,the tangent and normal are perpendicular to each other,therefore_____

Answer 1

Answer:

The equation of tangent to an ellipse is given by y=mx±  

a  

2

m  

2

+b  

2

 

​  

, m being the slope.

Here, a=4 and b=3, so the equation becomes y=mx±  

16m  

2

+9

​  

 

Similarly, the normal equation looks like y=mx±  

a  

2

+b  

2

m  

2

 

​  

 

m(a  

2

−b  

2

)

​  

 

​  

 

Here, the equation becomes y=mx±  

16+9m

​  

 

7m
