trig function The ratio of the sine of any angle within any specific triangle and the length for the opposite side is a constant.

\(\large{ \frac {sinA}{a}=\frac {sinB}{b}=\frac {sinC}{c} }\)

or three separate equations:

\(\large{ \frac {sinA}{a}=\frac {sinB}{b} }\)

\(\large{ \frac {sinA}{a}=\frac {sinC}{c} }\)

\(\large{ \frac {sinB}{b}=\frac {sinC}{c} }\)
