sin10°+sin20°+sin30°+sin40°+sin50°+……+sin2000°=?
(sin10°+sin50°)/sin35°sin55°的值
2 sin10*sin30*sin50*sin70=?
sin10°+sin20°+sin40°+sin50°+sin70°+sin80°求步骤加答案各方学霸求解答谢谢啦!
sin20°×cos7o°+sin10°×sin50°的值
sin20°cos70°+sin10°sin50°
求解:sin20~cos70~+sin10~sin50~(“~”代表“度”)=
sin20°cos70°+sin10°sin50°等于
sin10°sin30°sin50°sin70°=?
(sin10°+sin20°cos30°)/(cos10°-sin20°sin30°) 值
sin40°cos10°-SIN10°SIN50°的值是
sin20°cos70°+sin10°sin50°的值是( )
