Once upon a time, in a small classroom filled with eager math students, there was a worksheet called the Double Angle Identities Worksheet. It sat patiently on the teacher's desk, waiting to be handed out and challenged the students' understanding of trigonometry.

The worksheet was no ordinary piece of paper; it held the power to unlock the secrets of double angles and their identities. With each question, it aimed to test the students' knowledge and push them to dive deeper into the realm of trigonometric functions.

As the students received the worksheet, their eyes widened with a mix of excitement and trepidation. They knew that this worksheet would require them to think critically and apply their knowledge in unique ways. It was not going to be an easy task, but they were determined to conquer it.

With pencils in hand, they began to tackle the first question. The worksheet challenged them to find the value of sin(2θ) given the value of sin(θ). It required them to dig through their memory banks and recall the double angle identities they had learned in previous lessons.

1. Find the value of sin(2θ) when sin(θ) = 0.5.

  1. Use the double angle identity for sine: sin(2θ) = 2sin(θ)cos(θ).
  2. Substitute the value of sin(θ) into the equation: sin(2θ) = 2(0.5)cos(θ).
  3. Simplify further: sin(2θ) = cos(θ).

They diligently followed the steps, working through the problem and arriving at the correct answer. The satisfaction of solving the first question fueled their determination to conquer the rest of the worksheet.

2. Find the value of cos(2θ) when cos(θ) = -0.8.

  1. Use the double angle identity for cosine: cos(2θ) = cos²(θ) - sin²(θ).
  2. Substitute the value of cos(θ) into the equation: cos(2θ) = (-0.8)² - sin²(θ).
  3. Remember the Pythagorean identity: sin²(θ) + cos²(θ) = 1. Rearrange the equation to solve for sin²(θ): sin²(θ) = 1 - cos²(θ).
  4. Substitute the value of cos(θ) into the rearranged equation: sin²(θ) = 1 - (-0.8)².
  5. Simplify further: sin²(θ) = 1 - 0.64.
  6. Calculate sin(θ) by taking the square root of both sides: sin(θ) = √(1 - 0.64).
  7. Finally, substitute the value of sin(θ) into the original equation: cos(2θ) = (-0.8)² - (0.6)².

The students continued to work through the questions, each step bringing them closer to unlocking the full potential of double angle identities. They marveled at how these identities allowed them to express trigonometric functions in terms of other trigonometric functions, opening up a world of possibilities.

As they completed the last question, the students felt a sense of accomplishment wash over them. The Double Angle Identities Worksheet had challenged them, pushed them outside their comfort zones, and expanded their understanding of trigonometry.

The worksheet may have been just a piece of paper, but it had become a symbol of their growth and determination. It had taught them that with perseverance and a willingness to explore, they could overcome even the most daunting challenges.

And so, as the students handed in their completed worksheets, they thanked the Double Angle Identities Worksheet for its guidance and the valuable lessons it had imparted.
