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...

关于三角函数的值可以直接在计算器上按sin或者cos或者tan,然后再直接按数字,是多少度的就直接按什么数字.sin30°就先按sin键接着按30再按=号就可以得出结果.例题意思:求出tan40°到小数点后三位的近似值.在计算器上按tan然后按40按=号,若小数点后第四位数字大于或者等于5则第三位数进一,反之则不进一直接写...
