SUMMARY
The discussion centers on the application of the substitution rule, also known as the Change of Variables Theorem, to vectorial functions. A specific example is provided, where the integrand is a vector function composed of three components: \(2(x-1)^2\vec{i}\), \(cos(x)sin(x)\vec{j}\), and \((2x+3)^2\vec{k}\). The solution involves treating each component separately by defining new variables for each, such as \(u = x-1\), \(v = sin(x)\), and \(w = 2x+3\). This approach confirms that the substitution rule is applicable to vectorial functions in a similar manner as it is for scalar functions.
