〖1/1算式〗
作业:求算式 (sqrt(2-sqrt(3))/2)/(1-(sqrt(2-sqrt(3))/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2) 的值.
题型:数学计算
解:
(sqrt(2-sqrt(3))/2)/(1-(sqrt(2-sqrt(3))/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=(sqrt(2-sqrt3)/2)/(1-(sqrt(2-sqrt(3))/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=(sqrt0.267949/2)/(1-(sqrt(2-sqrt(3))/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/(1-(sqrt(2-sqrt(3))/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/(1-(sqrt(2-sqrt3)/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/(1-(sqrt0.267949/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/(1-0.258819^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/0.933013+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/0.933013+(1-(sqrt(2-sqrt3)/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/0.933013+(1-(sqrt0.267949/2)^2)/(sqrt(2-sqrt(3))/2)
=0.258819/0.933013+(1-0.258819^2)/(sqrt(2-sqrt(3))/2)
=0.258819/0.933013+0.933013/(sqrt(2-sqrt(3))/2)
=0.258819/0.933013+0.933013/(sqrt(2-sqrt3)/2)
=0.258819/0.933013+0.933013/(sqrt0.267949/2)
=0.258819/0.933013+0.933013/0.258819
=0.277401+0.933013/0.258819
=0.277401+3.604886
=3.882287 答案:(sqrt(2-sqrt(3))/2)/(1-(sqrt(2-sqrt(3))/2)^2)+(1-(sqrt(2-sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2)=3.882287你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
