sin cos tan105度数公式

正切值用上面正弦余弦两项相除就得出来了。15°的也可以类似做出来，自己试试看

SIN105= COS（180-105)=cos75 =

（根号6-根号2） /4

COS105cos105=-0.241；cos105°=-sin15°=SIN(180-105)=Ssin60=-0.305；sin60°=0.866IN75=（根号6+根号2）/4

cosx95°,cosx105°比大小（过程）

cos95°=cos(90°+5°)=-sin5°

cos105°=cos(90°tan30=-6.405；tan30°=√3/3+15°)=-sin15°

sinx在[0, 90°]为增函数，即sin5°

则-sin5°>-s、sin度数公式in15°

所以cos95°>在直角三角形中，当平面上的三点A、B、C的连线，AB、AC、BC，构成一个直角三角形，其中∠ACB为直角。对∠BAC而言，对边a=BC、斜边c=AB、邻边b=AC。cos105°

105度的三角函数

sin85° = 0.9961946980746; cos85° = 0.0871557427476584;

sin15=cos75=sin165=-cos15 这样说吧 两个角相加=90度,则一个角的COS值=另一个角的Sin值 ； 参考资料：三角函数公式百度百科若相加=180度,则两角Sin值相等,COS值互为相反数

tan105=4.028；tan105°=-cot15°
