The six basic trigonometric functions are:

1. Sine \(\displaystyle{\left({\sin}\right)}\)

2. Cosine \(\displaystyle{\left({\cos}\right)}\)

3. Tangent \(\displaystyle{\left({\tan}\right)}\)

4. Cotangent \(\displaystyle{\left({\cot}\right)}\)

5. Secant \(\displaystyle{\left({\sec}\right)}\)

6. Cosecant \(\displaystyle{\left({\csc}\right)}\)
