Sine and cosine are both trigonometric functions used to calculate angles in a right triangle. The main difference is that sine calculates the ratio of the opposite side to the hypotenuse, while cosine calculates the ratio of the adjacent side to the hypotenuse.
To find an angle using sine or cosine, you will need to know the lengths of two sides of a right triangle. You can then use the inverse function of sine or cosine (arcsine or arccosine) to find the angle measure.
No, sine and cosine can only be used to find angles in right triangles. For non-right triangles, you will need to use other trigonometric functions such as tangent or the law of sines or cosines.
The range of values for both sine and cosine is -1 to 1. This means that the ratio of any two sides of a right triangle will always be between -1 and 1, regardless of the size of the triangle.
Calculations using sine and cosine can be extremely accurate if the values used are precise. However, rounding errors or imprecise measurements can lead to slightly inaccurate results.
