The Six Trigonometric Functions
Muhtasari
Additional Mathematics extends trigonometry from the three familiar ratios to all six functions, defined for angles of any size. The three new ones (secant, cosecant and cotangent) are just reciprocals of the originals, and together they unlock a richer set of identities and equations.
In this lesson you will know and use the six trigonometric functions (sine, cosine, tangent, secant, cosecant and cotangent) of angles of any magnitude.
Malengo
- Know and use the six trigonometric functions (sine, cosine, tangent, secant, cosecant and cotangent) of angles of any magnitude.
