To solve the definite integral \(\int_{-1}^{1} \left( \frac{2x}{3} + \frac{3}{x^4} \right) \, dx\), we need to evaluate each term separately.First, let's consider the integral of the first term:
Since
is an odd function (i.e., \(f(-x) = -f(x)\)), the integral of an odd function over a symmetric interval around zero is zero:
Next, let's consider the integral of the second term:
Similarly,
is also an odd function. Therefore, its integral over the interval
is also zero:
Since both integrals are zero, the value of the original definite integral is:
Thus, the answer is:
