tan(-23派/6)的解答步骤
tan(－23π/6)=>>负角公式==－tan(23π/6)=－tan(4π－π/6)=>>2kπ的公式==－tan(－π/6)=tan(π/6)=√3/3.

tan(-23派/6) = tan(-4派+派/6) = tan(派/6)= √3/3

=tan(-23派/6+4派)=tan(派/6)=根号3/3

tanx的周期为π，所以tan（-23π/6）=tan（-24π/6+π/6)=tan(π/6)=√3/3

诱导公式：tan(-23π/6)= -tan(23π/6)= -tan(4π - π/6)= -tan(-π/6)= tan(π/6)= √3/3
