Welcome, dear reader, to the land of Cofunctions! Now, we know what you’re thinking. “Cofunctions? Sounds like something out of a math class I skipped in high school!” Well, fear not, we promise it’s less scary than it sounds. Let’s dive in, shall we?

Cofunction Calculation Formula
To calculate the cofunction of an angle in degrees, we use this nifty little formula:
cofunction = 90 - function
Simple, right?
Cofunction Types and Interpretations
| Category | Range | Interpretation |
|---|---|---|
| Sine and Cosine | 0 to 90 degrees | These bad boys are complementary |
| Tangent and Cotangent | 0 to 90 degrees | Also complementary, but a bit more complex |
| Secant and Cosecant | 0 to 90 degrees | They’re inverse functions of sine and cosine |
Cofunction Examples
| Individual | Calculation | Result | Commentary |
|---|---|---|---|
| John Doe | Cosine 45 degrees | 0.707 | John might be average, but his cosine is on point! |
| Jane Doe | Tangent 30 degrees | 0.577 | Jane’s got a way with tangents, doesn’t she? |
Cofunction Calculation Methods
| Method | Advantages | Disadvantages | Accuracy |
|---|---|---|---|
| Direct Calculation | Fast and easy | Requires a scientific calculator | High |
| Graphing | Visual and intuitive | Requires graph paper and patience | Moderate |
