Integral of (32/((x^2)(sqrt(16-(x^2)))))dx

In summary, the integral of (32/((x^2)(sqrt(16-(x^2)))))dx is equal to 16arcsin(x/4) + C, where C is the constant of integration. To solve this integral, the substitution method can be used. The integral is not defined for all values of x, but only for values of x between -4 and 4. The indefinite integral of the function is equal to 16arcsin(x/4) + C. The integral has significance in finding the area under the curve and in solving differential equations and other mathematical problems.

Problem Statment:
Int (32/((x^2)(sqrt(16-(x^2)))))dx

Problem Attempt:
a = 4 x = 4sin(w) w = theta
dx = 4cos(w)

Worked the problem down to:
2*int(1/(sin^2(w)))dw

Hi RUStudent! :smile:

(have an integral: ∫ and a square-root: √ and a squared: ² :smile:)

erm … how about 1/sin²w = cosec²w? :redface:
 

FAQ: Integral of (32/((x^2)(sqrt(16-(x^2)))))dx

What is the integral of (32/((x^2)(sqrt(16-(x^2)))))dx?

The integral of (32/((x^2)(sqrt(16-(x^2)))))dx is equal to 16arcsin(x/4) + C, where C is the constant of integration.

How do you solve the integral of (32/((x^2)(sqrt(16-(x^2)))))dx?

To solve this integral, you can use the substitution method by letting u = x/4 and du = dx/(4sqrt(16-(x^2))). Then, the integral becomes 8*int(1/(u^2)*du), which can be easily solved using the power rule.

Is the integral of (32/((x^2)(sqrt(16-(x^2)))))dx defined for all values of x?

No, the integral is not defined for all values of x. It is only defined for values of x such that 16-(x^2) > 0, which means that x must be between -4 and 4.

Can you find the indefinite integral of (32/((x^2)(sqrt(16-(x^2)))))dx?

Yes, the indefinite integral of (32/((x^2)(sqrt(16-(x^2)))))dx is equal to 16arcsin(x/4) + C, where C is the constant of integration.

What is the significance of the integral of (32/((x^2)(sqrt(16-(x^2)))))dx?

The integral represents the area under the curve of the given function. It can also be used to find the antiderivative of the function, which is useful in solving differential equations and other mathematical problems.
