〖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))
=0.277401+(1-(sqrt(2-(sqrt(3))/2)^2)/(sqrt(2-sqrt(3))/2))
=0.277401+(1-(sqrt(2-(sqrt3)/2)^2)/(sqrt(2-sqrt(3))/2))
=0.277401+(1-(sqrt(2-1.732051/2)^2)/(sqrt(2-sqrt(3))/2))
=0.277401+(1-(sqrt1.133974^2)/(sqrt(2-sqrt(3))/2))
=0.277401+(1-1.133973673924/(sqrt(2-sqrt(3))/2))
=0.277401+(1-1.133973673924/(sqrt(2-sqrt3)/2))
=0.277401+(1-1.133973673924/(sqrt0.267949/2))
=0.277401+(1-1.133973673924/0.258819)
=0.277401+(-3.381339)
=-3.103938 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))=-3.103938你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
