Transcribed Image Text:The image contains trigonometric notations for the cosine values of two specific angles:
- "cos 45°"
- "cos 60°"
These denote the cosine values for angles 45 degrees and 60 degrees, respectively.
Cosine is one of the primary trigonometric functions and is defined for an angle in a right triangle as the length of the adjacent side divided by the length of the hypotenuse. For the angles given, the values can be derived as follows:
- \( \cos 45^\circ = \frac{\sqrt{2}}{2} \approx 0.707 \)
- \( \cos 60^\circ = \frac{1}{2} = 0.5 \)
These values are fundamental in trigonometry and are widely used in various applications within mathematics, physics, and engineering.
