Understanding Trigonometric Functions and Formulas
Trigonometry deals with the relationships between the angles and sides of triangles, especially right-angled triangles. The six fundamental trigonometric functions relate the angles of a triangle to the lengths of its sides.
1. Sine (sin)
The sine of an angle in a right-angled triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
Formula:
2. Cosine (cos)
The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.
Formula:
3. Tangent (tan)
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Formula:
4. Cosecant (csc)
The cosecant is the reciprocal of the sine function.
Formula:
5. Secant (sec)
The secant is the reciprocal of the cosine function.
Formula:
6. Cotangent (cot)
The cotangent is the reciprocal of the tangent function.
Formula:

Frequently Asked Questions (FAQs)
What are the Reciprocal Trigonometric Functions?
The reciprocal trigonometric functions are the reciprocals of the primary trigonometric functions:
- Cosecant (csc): Reciprocal of sine (csc θ = 1 / sin θ).
- Secant (sec): Reciprocal of cosine (sec θ = 1 / cos θ).
- Cotangent (cot): Reciprocal of tangent (cot θ = 1 / tan θ).
Why is the Tangent of 90 Degrees Undefined?
At 90 degrees (or π/2 radians), the cosine of the angle is zero. Since tan θ = sin θ / cos θ, dividing by zero makes the tangent function undefined at this angle.
Can I Enter Negative Angles?
Yes, the calculator accepts negative angles. Negative angles represent rotation in the opposite direction and are valid inputs for trigonometric functions.
What is the Range of Values for Trigonometric Functions?
- Sine and Cosine: Values range from -1 to 1.
- Tangent and Cotangent: Values range from negative infinity to positive infinity, with discontinuities where the functions are undefined.
- Cosecant and Secant: Values are less than or equal to -1 or greater than or equal to 1; they never take values between -1 and 1.
