Question #cd403
1 Answer
tangent line:
normal line:
Explanation:
Original equation:
slope of the tangent to y, or
In order to form a straight line equation,
we would need both the value of
In this case, we need to find
Substitute
Now, we can form equation of the tangent line
I will be using the gradient formula:
We know that
Normal line?
It is a line perpendicular to tangent line, in this case at
Find
form the equation using of the normal line.
Now, i will use another method
(of course, you still can use the method i showed above. Both yield the same answer)
We know that
We have
To find
Substitute
