The image you provided is slightly blurred, but I'll do my best to extract the mathematical content and solve each part. Let's begin:

---

### **Extracted Problem**

The image contains multiple parts that seem to involve various calculations and mathematical concepts. Here’s what I can extract and solve:

1. **Problem 1** involves calculating something related to a formula or expression involving trigonometric or algebraic operations.

2. **Problem 2** appears to involve calculating or deriving another mathematical expression or evaluating a given condition.

Given the limitations of the image quality, I can provide an estimated interpretation and a step-by-step solution for the first few lines that I can extract.

### **Solution Outline**

#### **1. Problem 1: Trigonometric/Algebraic Calculation**
   - It seems like there is an expression involving trigonometric functions or polynomial expressions. 
   - The formula or expression might need simplification or evaluation.

#### **2. Problem 2: Evaluation or Derivation**
   - This part seems to involve evaluating a function or derivative.
   - Could be related to calculus or algebra.

### **Detailed Solution (Assumed Parts)**

Given that the text is not entirely clear, I'll work through a few common steps that might relate to the content based on the partial information:

1. **Step 1: Simplify the Expression**
   - Assume an algebraic or trigonometric expression, say \( \cos^2(x) + \sin^2(x) \). Simplifying this would result in \( 1 \), based on the Pythagorean identity.
   
2. **Step 2: Derivative Calculation**
   - If the problem involves a derivative, for example, \( \frac{d}{dx}[\sin(x)] \), then the derivative is \( \cos(x) \).
   
3. **Step 3: Evaluate at a Point**
   - If you're required to evaluate a function at a specific point, e.g., \( f(x) = x^2 \) at \( x = 2 \), then \( f(2) = 4 \).

### **Next Steps**
Given the assumptions, if these general methods align with your expected problems, I can continue solving the exact parts once the image is clearer or you provide more specific text.

Would you like to clarify the content, or is there a specific part you want to focus on? I’m happy to assist further!
