Question

If y = sec(x), then dy/dx = ? ​

Answer 1

Answer:

Hope this helps you.......

Step-by-step explanation:

Y in terms of cos(x). We are familiar with cos(x) and know how to differentiate it. We know that sec(x) = 1/cos(x) = (cos(x))-1.

Answer 2

Answer:

the value of $\frac{dy}{dx}=\sec x \cdot \tan x$  when y = sec x

Step-by-step explanation:

Given :

we are given the expression

$y=\sec x$

To Find :

The value of  $\frac{dy}{dx}$

Solution :

Since we are given the expression that

                            $y=\sec x$

take derivatives both side

                          $\frac{d}{dx}y =\frac{d}{dx}\sec x$

since we know that the derivative of sec(x) = sec(x)tan(x)

so

                        $\frac{dy}{dx}=\sec x\cdot \tan x$

Hence we have calculated the value of $\frac{dy}{dx}=\sec x \cdot \tan x$
