基本函数有：Abs函数Atn函数Cos函数Exp函数Fix函数Int函数Log函数Rnd函数Sgn函数Sin函数Sqr函数Tan函数以下为导出函数函数由基本函数导出之公式Secant（正割）Sec(X)=1/Cos(X)Cosecant（余割）Cosec(X)=1/Sin(X)Cotangent（余切）Cotan(X)=1/Tan(X)InverseSine（反正弦）Arcsin(X)=Atn(X/Sqr(-X*X+1))InverseCosine（反余弦）Arccos(X)=Atn(-X/Sqr(-X*X+1))+2*Atn(1)InverseSecant（反正割）Arcsec(X)=Atn(X/Sqr(X*X-1))+Sgn((X)-1)*(2*Atn(1))InverseCosecant（反余割）Arccosec(X)=Atn(X/Sqr(X*X-1))+(Sgn(X)-1)*(2*Atn(1))InverseCotangent（反余切）Arccotan(X)=Atn(X)+2*Atn(1)HyperbolicSine（双曲正弦）HSin(X)=(Exp(X)-Exp(-X))/2HyperbolicCosine（双曲余弦）HCos(X)=(Exp(X)+Exp(-X))/2HyperbolicTangent（双曲正切）HTan(X)=(Exp(X)-Exp(-X))/(Exp(X)+Exp(-X))HyperbolicSecant（双曲正割）HSec(X)=2/(Exp(X)+Exp(-X))HyperbolicCosecant（双曲余割）HCosec(X)=2/(Exp(X)-Exp(-X))HyperbolicCotangent（双曲余切）HCotan(X)=(Exp(X)+Exp(-X))/(Exp(X)-Exp(-X))InverseHyperbolicSine（反双曲正弦）HArcsin(X)=Log(X+Sqr(X*X+1))InverseHyperbolicCosine（反双曲余弦）HArccos(X)=Log(X+Sqr(X*X-1))InverseHyperbolicTangent（反双曲正切）HArctan(X)=Log((1+X)/(1-X))/2InverseHyperbolicSecant（反双曲正割）HArcsec(X)=Log((Sqr(-X*X+1)+1)/X)InverseHyperbolicCosecantHArccosec(X)=Log((Sgn(X)*Sqr(X*X+1)+1)/X)InverseHyperbolicCotangent（反双曲余切）HArccotan(X)=Log((X+1)/(X-1))/2以N为底的对数LogN(X)=Log(X)/Log(N)所以,sin-1(x)可用Atn(X/Sqr(-X*X+1))来算,即sin-1(0.5)=Atn(0.5/Sqr(-0.5*0.5+1))算出来的结果是弧度制表示的如果想要表示为角度,则把结果乘以180/3.14159
