利用csc(x)=53csc(x)=53确定三角形的已知边。 csc(x)=1sin(x)=hypopp=53csc(x)=1sin(x)=hypopp=53 利用tan(x)=34tan(x)=34确定三角形的已知边。 tan(x)=oppadj=34tan(x)=oppadj=34 使用hyp=5hyp=5和opp=3opp=3求正弦函数的值。
In regard to their relative positions in the triangle, this is the ratio of the length of the side opposite angle CAB to the length of the hypotenuse. Label this ratio as opp/hyp=. Your screens should be similar to the ones below. ...
一、看看已知的边和需要求的边是对边、邻边还是斜边。 二、用上面的公式来决定用 正弦、余弦 或 正切。 三、正弦:求 对边/斜边,余弦:求 邻边/斜边, 或 正切:求 对边/邻边。公式里其中一个值是未知的边长。 四、用计算器和你的 代数 知识来解 例子 再看一些例子: 例子:求飞机的高度。 飞机的距离是...
If a triangle contains two unknown sides, then more complex trigonometric formulas and algebraic proofs will have to be applied in order to find them. This same mathematical theorem can also be applied to physics problems like triangular force vectors. What Is a Right Triangle? A right angled ...
