Pi (π) divided by 4 is a mathematical expression that represents the ratio of the circumference of a circle to its diameter, divided by 4. The value of π is approximately 3.14159. Therefore, π divided by 4 is approximately 0.7854.
Mathematically, this can be expressed as:
π / 4 ≈ 0.7854
This value is often used in various mathematical and engineering calculations, particularly in trigonometry and geometry. For example, it appears in the formula for the area of a circle when the radius is squared and multiplied by π/4.
Understanding this value is essential for solving problems related to circles, angles, and periodic functions. It also plays a significant role in Fourier transforms and signal processing.
