Convert each degree measure to radians. Leave answers as multiples of π.


175°

Key Concepts

Degree to Radian Conversion

To convert degrees to radians, use the conversion factor π radians = 180 degrees. This means that to convert a degree measure, you multiply the degree value by π and then divide by 180. For example, to convert 175°, you would calculate (175 × π) / 180.

Simplifying Fractions

When converting degrees to radians, the resulting fraction can often be simplified. This involves finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by this value. Simplifying helps express the angle in its simplest form, making it easier to understand and use in further calculations.

Understanding π in Trigonometry

In trigonometry, π (pi) is a fundamental constant representing the ratio of a circle's circumference to its diameter. It is approximately equal to 3.14, but in trigonometric contexts, it is often left in terms of π to maintain exactness. Understanding how π relates to angles is crucial for working with radians, as it helps in visualizing and calculating circular motion and periodic functions.
