Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

![### Problem 25: Integration Exercise
Evaluate the following integral:
\[
\int \frac{dy}{\sqrt{e^{2y} - 1}}
\]
This integral requires applying techniques for solving integrals involving exponential functions under a radical. To solve it, we might need to consider appropriate substitutions or manipulation of the integrand.
**Steps to Evaluate:**
1. Consider substitution methods to simplify the expression under the square root.
2. Determine if trigonometric or hyperbolic identities can simplify the integrand.
3. Apply the appropriate integral formulas once the integrand is simplified.
This exercise helps in understanding advanced integral computation techniques and will explore integral properties involving exponential functions.
**Note:** The answer to this integral can often be found in integral tables or by using computer algebra systems when manual computation is complex. Integrating similarly structured functions broadens your approach to solving integrals analytically.
