You can use Excel to calculate the trigonometric function of angle; The specific operation method is:
Operating tools: computer win7, Excel2007.
1. First, take the sine of the angle as an example, and open Excel to make a table as shown in the figure.
2. Now enter "= sin (d3 * 3.14159265358979/180)" in the F3 cell, as shown in the figure.
3. At this time, you can see the sine value corresponding to the degree.
4. Cosine and tangent can also do the same, as shown in the figure.
5. If you want to calculate cotangent, enter "=1/tan (d3 * 3.14159265358979/180)" in F6, as shown in the figure.
6. Finally enter the car to see the results, as shown in the figure.
