Question

product of slope of tangent and normal is equal to -1......true or false?​

Answer 1

Answer:

The answer is true....

Answer 2

True, the given statement is true.

Step-by-step explanation:

The product of slope of tangent and normal = - 1 (True/False)

We know that,

The slope of tangent = $\dfrac{dy}{dx}$

and

The slope of normal = $\dfrac{-1}{\dfrac{dy}{dx}}$

∴ The slope of tangent × The slope of normal

= $\dfrac{dy}{dx}$ × $\dfrac{-1}{\dfrac{dy}{dx}}$

= - 1

∴ The product of slope of tangent and normal = -1, true

Thus, true, the given statement is true.
