For real values of X , sin(X) returns real values in the interval [-1, 1]. Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. The plus–minus sign (also, plus or minus sign), ±, is a mathematical symbol with multiple meanings. In mathematics, it generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction.

2020-07-26 · Sin, cos and tan. Before we can use trigonometric relationships we need to understand how to correctly label a right-angled triangle. There are three labels we will use:
Because you spend a ton of time in pre-calculus working with trigonometric functions, you need to understand ratios. One important ratio in right triangles is the sine. The sine of an angle is defined as the ratio of the opposite leg to the hypotenuse. In symbols, you write Here’s what the ratio looks like: In […] Notice in particular that sine and tangent are odd functions, being symmetric about the origin, while cosine is an even function, being symmetric about the y-axis. The fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions.

sin 方法返回一个 -1 到 1 之间的数值，表示给定角度（单位：弧度）的正弦值。 由于 sin 是 Math 的静态方法，所以应该像这样使用： Math.sin() ，而不是作为你创建的 Math 实例的方法。
