根据锐角三角函数的概念，即可发现随着一个锐角的增大，它的对边在逐渐增大，它的邻边在逐渐减小，故正弦值随着角的增大而增大，余弦值随着角的增大而减小．解 结论：锐角的正弦值随角度的增大而增大。即:随着锐角θ的增长，sinθ的值随角度的增大而增大。
start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. now the value of y becomes 1 since it touches the circumference of the circle. therefore the value of y becomes 1. \(\begin{array}{l}\sin \theta = \frac{y}{1} = \...

sin75度等于0.9659。在单位圆中，正弦函数sinθ表示一个角度θ对应的边长与半径的比值。具体到sin75度，我们首先需要知道三角函数的值和角度有关，不同角度的正弦值通过三角函数表或通过现代电子计算工具可以得到。在这里，sin75度的值约等于0.9659。这是因为当角度在0到90度之间变化时，...
$$ \sin(\theta) = \frac{\text{对边}}{\text{斜边}} $$ 在实际计算中，我们通常使用计算器或数学软件来获取特定角度的正弦值。对于常见的角度，如°、30°、45°、60°和90°，它们的正弦值可以通过记忆或查表得到。2. 余弦函数（cos）：余弦函数定义为直角三角形中，邻边（即与角度相邻的边）与斜边...
"θ"表示角度,sinθ表示θ角的正弦值。简单点说，把θ放在一个直角三角形中，sinθ就表示θ角所对的直角边的数值与斜边数值的比值。（如果θ=90°，sinθ=1）比如直角三角形勾股弦3、4、5，假设4、5边所夹的夹角为θ，则sinθ=3/5
