The tutorial emphasizes the importance of understanding degrees and radians in trigonometric calculations within Excel. Degrees divide a circle into 360 parts, whereas radians measure angles based on arc length equaling the circle's radius, with a full circle as 2Ï radians. Excel includes functions like RADIANS to convert degrees to radians, and DEGREES for the reverse. Additionally, users can format outputs for easier readability, limiting decimals to two places, and apply rounding functions to simplify excessively precise outputs.
A degree is a unit for measuring angles, divided into 360 parts, with a right angle equaling 90 degrees. A radian measures the angle formed when the arc length matches the radius.
In Excel, trigonometric functions like SIN, COS, and TAN require angles in radians. The RADIANS function converts degrees to radians, while the DEGREES function does the reverse.
To format Excel results, after using the RADIANS function, select the output cells, right-click to choose Format Cells, and under the Category, select Custom to limit decimal places.
Using the ROUND or ROUNDDOWN functions helps simplify the results obtained from the DEGREES function, which may show excessively long decimal outputs.
