tan(3π/5)和tan(-3π/5)大小tan(3π/5)和tan(-3π/5)大小tan(3π/5)和tan(-3π/5)大小解析:tan(3π/5)和tan(-3π/5)大小3π/5=108度
tan(3π/5)和tan(-3π/5)大小
tan(3π/5)和tan(-3π/5)大小
tan(3π/5)和tan(-3π/5)大小
解析:
tan(3π/5)和tan(-3π/5)大小
3π/5=108度,在第二象限,tan(3π/5)是负数
tan(-3π/5)=-tan(3π/5)是正数,
tan(3π/5)
tan(3π/5)小于tan(-3π/5)
tan(3π/5)=tan(-3π/5)
tan(3π/5)和tan(-3π/5)大小
比较tan(-π/5)与tan(-3π)的大小
已知tan(x-y)=2,tan(y+π/5)=3,则tan(x+π/5)等于
tan(a-3/π) =2 tan(3/π-B)=2/5 求tan(a+b)=
tan(α+β)=3/5 tan(β-4/π)=1/4 则tan(α+4/π)等于多少
tan(a+b)=2/5 tan(a+π/4)=3/22 求tan(b-π/4)
若tan(α+β)=3/5,tan(β-(π)/4)=1/4,则tan(α+(π)/4)=?
tan(α+β)=3/5,tan(β-π/4)=1/4,则tan(α+π/4)
tan=3,π
tan(-20/3π)
不通过求值,如何比较2个正切函数的大小tan(-1/5π)和tan(-3/7π)tan(75/11π)和tan(-58/11π)比较这两组正切值的大小
tan?=1/2 tan?=1/3 tan?=1/4 tan?=1/5 tan?=1/6
tan(-5分之π)与tan(-7分之3π)的大小
tan(π/6-2)=根号3/2,求tan(5π/6+2)的值
tan(-π/5)与tan(3π/7)哪个大
若tan(α+π/4)=-3/5,求tan(α-π/4)的值
tanα=2则tan(α-π/6)=5根号3-8,
已知β-a=γ-β=π/3,求tanαtanβ+tanβtanγ+tanγtanα的值
