Answer: $r=\dfrac{C}{2\pi}$ , where C is the circumference of the circle.

Step-by-step explanation:

We know that the formula to calculate the circumference of the circle is given by :-

$C=2\pi r$ , where r is the radius of the circle.

To find the expression for r , we divide $2\pi$ on the both sides , we get

$\dfrac{C}{2\pi}=r$

$r=\dfrac{C}{2\pi}$

Hence, the expression for r will be:-

$r=\dfrac{C}{2\pi}$ , where C is the circumference of the circle.

Consider the differential equation: dy/dx = (y-2)(x^2+1)

Klio2033 [76]

Answer:

Step-by-step explanation:

Given,

$\dfrac{dy}{dx}=(y-2)(x^2+1)$ ...(i)

Differentiating w.r. to x.

$\dfrac{d^2y}{dx^2}= (y-2)(2x)+ (x^2+1)\dfrac{dy}{dx}$

From equation (1)

$\dfrac{d^2y}{dx^2}= (y-2)(2x)+ (x^2+1)^2(y-2)$

Now, at the point (1,3)

$\dfrac{d^2y}{dx^2}= (3-2)(2\times 1)+ (1^2+1)^2(3-2)$

$\dfrac{d^2y}{dx^2}=6$
