化简cos^2(-α)-[tan(360°+α)/sin(-α)]
化简cos^2(-α)-[tan(360°+α)/sin(-α)]
化简cos^2(-α)-[tan(360°+α)/sin(-α)]
cos^2(-α)-[tan(360°+α)/sin(-α)]
=cos^2(α)+tanα/sinα
=cos^2(α)+1/cosα
这已经是够简的了,若还有问题可以直接HI我.
化简cos^2(-α)-[tan(360°+α)/sin(-α)]
已知cos(2α+β)=3cosβ,化简tanα×tan(α+β)
化简:(sin²αtanα+cos²α/tanα+2sinαcosα)sinαcosα
化简(sinα)^2tanα+cosα+(cosα)^2*1/tanα+2sinαcosα
化简:(1)sin(-α+180°)-tan(-α)+tan(-α+360°)/tan(α+180°)+cos(-α)+cos(α+180°)(2)sin^2(α+π)cos(-α+π)/tan(α+π)+tan(α+2π)cos^3(-α-π)
