Detailed Solutions for Chapter 23.1

Now, let's get to the heart of the matter: the solutions. We'll go through some common types of problems you might encounter in Chapter 23.1 and provide step-by-step solutions. Remember to practice these problems on your own to reinforce your understanding. Don't just memorize the steps; try to understand the logic behind each step so you can apply the same principles to different problems.

Example Problem 1: Trigonometry

Problem: If sin θ = 3/5, find the value of cos θ.

Solution:

1. We know that sin²θ + cos²θ = 1.
2. Substitute the given value: (3/5)² + cos²θ = 1.
3. Simplify: 9/25 + cos²θ = 1.
4. Subtract 9/25 from both sides: cos²θ = 1 - 9/25 = 16/25.
5. Take the square root: cos θ = √(16/25) = 4/5.

So, the value of cos θ is 4/5.

Example Problem 2: Geometry

Problem: Find the area of a triangle with base 10 cm and height 8 cm.

Solution:

1. The formula for the area of a triangle is (1/2) × base × height.
2. Substitute the given values: Area = (1/2) × 10 cm × 8 cm.
3. Simplify: Area = 5 cm × 8 cm = 40 cm².

So, the area of the triangle is 40 cm².

Example Problem 3: Mensuration

Problem: Find the volume of a cube with side length 6 cm.

Solution:

1. The formula for the volume of a cube is side³.
2. Substitute the given value: Volume = (6 cm)³.
3. Simplify: Volume = 6 cm × 6 cm × 6 cm = 216 cm³.

So, the volume of the cube is 216 cm³.

Tips and Tricks for Solving Chapter 23.1 Problems

• Understand the Formulas: Make sure you know all the relevant formulas by heart.
• Draw Diagrams: Visualizing the problem can make it easier to understand.
• Break Down Complex Problems: Divide the problem into smaller, manageable parts.
• Practice Regularly: The more you practice, the better you'll become.
• Check Your Answers: Always double-check your work to avoid mistakes.

Importance of Regular Practice

Regular practice is crucial for mastering Chapter 23.1. The more you practice, the more comfortable you'll become with the different types of problems and the more confident you'll be in your ability to solve them.
