tan(-23派/6)的解答步骤

=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

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

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.
