The equation of the normal line is: y=−13x+73
Explanation:
Compute y'(x):
y'(x)=3x2
The slope, m, of the tangent line is at the point (1, 2) is y'(1):
m=y'(1)=3(1)2=3
The slope, n, of the normal to the curve is:
n=−1m=−13
Start with the slope-intercept form of the equation of a line:
y=mx+b
Substitute, 2 for y, −13 for m, 1 for x, and the solve for b:
2=−13(1)+b
b=73

Answer:
x=y
Step-by-step explanation:
The equation of the curve is ....... (1)
Now, we have to calculate the equation of normal to the curve (1) at point ().
First of all, we have to calculate the slope of the normal at that point.
Differentiating equation (1) with respect to x we get,
⇒
⇒ -
⇒.
Hence, the equation of the normal is
(y-a/2√2)=1(x-a/2√2)
⇒ x=y. (Answer)
