Sin, Cos & Tan – Triangle Formulas You will need to understand sin, cos, and tan triangle formulas for your exam. Remember that the hypotenuse is the side of the triangle opposite the right angle. The adjacent side is next to the angle being measured. ...
sin:正弦 tan:正切 cos:余弦 应用场景:这三个词是三角函数的基本组成部分,在数学、物理、工程学等多个领域中都有广泛应用。它们用于描述直角三角形中边长的关系,以及在周期性现象(如波动、振动)中的分析。 造句例句: 中文:在直角三角形中,正弦、余弦和正切是三种基本的三角函数。 英文:...
cos(余弦)是邻边与斜边之比。即cos的值等于直角三角形中,与给定角相邻的那条边(邻边)的长度除以斜边的长度。 tan(正切)是对边与邻边之比。也就是说,tan的值等于直角三角形中,对边的长度除以邻边的长度。 英文解释: In a right triangle, the trigonometric functions sin, cos, and tan correspond to spe...
Sine, cosine and tangent, often shortened to sin, cos, and tan in mathematical operations and on calculator keys, are the most basic trigonometric functions. All three are based on the properties of a triangle with a 90-degree angle, also known as a right triangle. By knowing the sides of...

Sin, Cos and Tan This section looks at Sin, Cos and Tan within the field of trigonometry. A right-angled triangle is a triangle in which one of the angles is a right-angle. The hypotenuse of a right angled triangle is the longest side, which is the one opposite the right angle. The...
三角函数sincostan的定义三角函数 The trigonometric functions sine, cosine, and tangent are fundamental concepts in mathematics that are extensively used in various fields such as physics, engineering, and computer science. These functions are defined based on the ratios of sides of aright triangle ...
tan, sin, and cos: A Friendly Guide! Imagine you're looking at a right triangle, like the one on a corner flag. You've got your 90-degree angle, and then two other angles that are smaller. Let's call one of those angles "alpha" (α). · sin α (sine): This is like the ...
