What is the exact value of sin 5° and how do you find it? Type in the Google search engine: sin(5 degrees). It will compute it for you. It appears you pasted something that the ASCII didn’t translate. You’ll need to type out the value for the angle.
The Correct Answer and Explanation is:
The exact value of sin(5°) cannot be simplified into a nice, neat fraction or rational expression. It’s generally calculated numerically. However, it is possible to compute it using various mathematical methods, such as the Taylor series expansion or a calculator.
For practical purposes, we often use a calculator or a computer to find this value. Typing sin(5°) into a Google search or a scientific calculator will give you a numerical result. The value of sin(5°) is approximately:
sin(5°) ≈ 0.0872
Explanation of How to Find sin(5°):
- Using a Calculator or Google:
The simplest method to find sin(5°) is by using a scientific calculator or an online tool like Google. Typing sin(5 degrees) into Google will immediately give the value. This method uses algorithms for trigonometric functions that give you an accurate approximation. - Taylor Series Expansion:
For more detailed mathematical computation, you can use the Taylor series for sine. The Taylor series for sin(x) around x = 0 is given by: sin(x)=x−x33!+x55!−x77!+⋯\sin(x) = x – \frac{x^3}{3!} + \frac{x^5}{5!} – \frac{x^7}{7!} + \cdotssin(x)=x−3!x3+5!x5−7!x7+⋯ When x is measured in radians, you can substitute x=5∘x = 5^\circx=5∘ (which is approximately 5×π1805 \times \frac{\pi}{180}5×180π radians). However, for very small angles like 5°, this series converges rapidly and gives a good approximation after just a few terms. - Unit Circle:
The sine of any angle can also be found by referring to the unit circle. For angles that are not commonly known, we rely on numerical methods, as there’s no simple geometric representation for sin(5°) without approximation.
Ultimately, for most applications, using a calculator or online tool is the quickest and easiest way to get an accurate value for sin(5°).
