Therefore since the trig equation we are solving is sin and it is positive (0.5), then we are in the 1st and 2nd quadrants. We have already found the first solution which is the acute angle from ...

These three equations are true for all right-angled triangles. They are known as the three trigonometric ratios because they show how large one side is compared to the other based on an angle Ɵ ...

The syntax for the TAN function is: Number: The angle for radians for which you want the tangent. What is Math and Trig functions in Excel? In Microsoft Excel, the Math and Trig functions allow ...

Most trigonometry students look at triangles on a flat surface. However, people from ancient astronomers to modern navigators calculated the arc lengths and angles of triangles on a sphere. They used ...
