Question

if y=sinx then dy/dx at x=π/2 will be
​

Answer 1

Answer:

Here is your answer

Explanation:

Answer 2

$\frac{dy}{dx}$ at x = π/2 is equal to 0.

Given,

y = Sin x

To Find,

$\frac{dy}{dx}$ at x = π/2

Solution,

y = Sin x

Differentiating both sides we get,

$\frac{dy}{dx} = \frac{d(Sin x)}{dx}$

$\frac{dy}{dx}$ = Cos x                (as we know differentiation of sin θ is cos θ)

Now we have to find the value of $\frac{dy}{dx}$ when x = π/2

Substituting the value of x = π/2, we get

$\frac{dy}{dx}$ = Cos (π/2)

$\frac{dy}{dx}$ = 0

Thus, the final answer is 0.
