## Trigonometric Function Analysis and Problem Solving

### Problem 1: Graphing the Function
**Task:**
Graph one cycle of the trigonometric function \( f(x) = 2\cos(x - \pi) + 1 \).

### Problem 2: Function Characteristics
**Task:**
Find the period, amplitude, phase shift, and vertical shift of the function in Problem 1.

### Problem 3: Solving Trigonometric Equations
**Task:**
Solve the equation, giving the exact solutions which lie in the interval \([0, 2\pi)\):
\[ \cos(2x) = 5\sin(x) - 2 \]

### Problem 4: Solving Trigonometric Equations
**Task:**
Solve the equation, giving the exact solutions which lie in the interval \([0, 2\pi)\):
\[ 2\tan(x) = 1 - \tan^2(x) \]

### Problem 5: Solving for Sides and Angles
**Task:**
Solve for the remaining side(s) and angle(s), if possible. The pairs \((\alpha, a)\), \((\beta, b)\), and \((\gamma, c)\) are angle-side opposite pairs.

Given:
\[ \alpha = 22^\circ, \quad \beta = 33^\circ, \quad a = 4 \]

### Diagrams and Graphs:
- **Function Graph:** (No diagram provided in the text, manual graphing or use of graphing software recommended.)
- **Equations and Solutions:**
    - Visualization of solutions on the unit circle might be helpful for Problems 3 and 4.
    - Triangle diagrams showing angles and sides for Problem 5 may assist in solving using the Law of Sines or the Law of Cosines.

Understanding and visualizing these trigonometric concepts will aid in effectively solving and graphing the given problems.
