Riemann Sum

Riemann Sums is a special type of approximation of the area under a curve by dividing it into multiple simple shapes like rectangles or trapezoids and is used in integrals when finite sums are involved. Figuring out the area of a curve is complex hence this method makes it simple. Usually, we take the help of different integration methods for this purpose. This is one of the major parts of integral calculus.

Riemann Integral

Bernhard Riemann's integral was the first systematic description of the integral of a function on an interval in the branch of mathematics known as real analysis.

Question

Welcome to our educational resource on advanced calculus integral problems.

### Advanced Integral Problems

#### Problem 1
Evaluate the integral from 1 to 3 of the function:
\[ \int_{1}^{3} \frac{1}{x[\ln(3x)]^2} \, dx \]

This problem involves an integral with a logarithmic function nested within the integrand. To solve this, consider using substitution methods that simplify the logarithmic components.

#### Problem 2
Evaluate the integral of a polynomial function multiplied by an exponential function:
\[ \int (x^2 - 5x + 2)e^{x} \, dx \]

This integral can be approached using integration by parts, which is particularly useful when dealing with products of polynomials and exponentials.

### Explanation of Methods:
For Problem 1: You may want to start with the substitution \[ u = \ln(3x) \]. Then du will aid in simplifying the integral's boundaries and components.

For Problem 2: Apply integration by parts, using the formula \[ \int u \, dv = uv - \int v \, du\]. Choose appropriate $u$ and $dv$ parts to systematically reduce and solve the integral.

The following are integral problems that require evaluation. Each problem features a unique integrand and would typically be found in a calculus course focused on integral calculus.

14h) \[\int \sin^{-1} (3x) \, dx\]

14i) \[\int e^{x^2} \sin (3x) \, dx\]

Each problem involves integrating functions, with the first problem involving the inverse sine function $\sin^{-1} (3x)$, and the second problem involving the product of an exponential function $e^{x^2}$ and a sine function $\sin (3x)$. These integrals may require advanced techniques of integration such as integration by parts, substitution, or recognizing patterns from integral tables.

To solve these integrals, one might need to apply such techniques strategically, possibly requiring the knowledge of special integrals or conversion to more workable forms.

For example:

1. The integral involving the inverse sine function may require trigonometric identities or a substitution to simplify the expression.
2. The integral with the exponential and sine functions might hint at using the method of integration by parts multiple times, or recognizing it as a form of a known result.

Students are encouraged to outline their problem-solving approach by identifying possible methods, performing step-by-step integration, and confirming their results.
