45kraadi

45kraadi is the Estonian expression for the angle of 45 degrees. In mathematics, 45 degrees is an acute angle equal to pi/4 radians. A line that forms a 45-degree angle with the x-axis has a slope of 1 (in the standard orientation) or −1 in other directions. In a square, the diagonals are at 45 degrees to the sides. In trigonometry, sin(45°) and cos(45°) both equal √2/2, and tan(45°) equals 1. Geographically or in navigation, a bearing of 45 degrees points toward the northeast.

Beyond its mathematical meaning, 45kraadi is used as a name in Estonian-language contexts for various projects, brands, or cultural ventures. Because it is a common phrase rather than a single, specific entity, references to 45kraadi typically require disambiguation to identify the exact subject.

In summary, 45kraadi denotes both a standard geometric angle and a recurring branding or naming choice in Estonian-speaking settings, reflecting the versatility of the term across technical and cultural domains.
