Use the angle in radians or degrees as needed
Find the sine value with a calculator or sine table
If the sine is a common angle, write it as an exact fraction or radical form
Examples: sin 0 = 0
Examples: sin 30° = 1/2
Examples: sin 45° = √2/2
Examples: sin 60° = √3/2
For angles without exact values, write the decimal as a fraction if required
Simplify the fraction if possible
If converting from decimal to fraction, place the decimal over a power of 10 and reduce
If the sine value is not rational, keep it in radical or decimal form instead of forcing a fraction
