Convert each degree measure to radians. Leave answers as multiples of π. See Examples 1(a) and 1(b). 30°

Guida verificata passo dopo passo

Recall the formula to convert degrees to radians: \(\text{radians} = \text{degrees} \times \frac{\pi}{180}\).

Substitute the given degree measure into the formula: \(30^\circ \times \frac{\pi}{180}\).

Simplify the fraction \(\frac{30}{180}\) by dividing numerator and denominator by their greatest common divisor, which is 30.

After simplification, express the result as a multiple of \(\pi\).

Write the final answer in the form \(\frac{\pi}{n}\) where \(n\) is the simplified denominator.

Degree to Radian Conversion

Degrees and radians are two units for measuring angles. To convert degrees to radians, multiply the degree measure by π/180. This conversion is essential because radians are the standard unit in many trigonometric applications.

Understanding π as a Constant

π (pi) is an irrational constant approximately equal to 3.14159, representing the ratio of a circle's circumference to its diameter. Expressing angles as multiples of π provides exact values rather than decimal approximations.
