Let's look at the graph of sinθ, cosθ , tanθ and their properties in A-Level Maths!

**Sinθ°**

Period:

360° (2*π)*

Domain:

x∝R

Range:

-1 ≤ y ≤ 1

One cycle occurs between 0 and *π*

** Cosθ°**

Period:

360° (2*π)*

Domain:

x∝R

Range:

-1 ≤ y ≤ 1

One cycle occurs between -*π/2* and 3*π/2*

**Tanθ°**

Period:

180° (*π)*

Range:

-1 ≤ y ≤ 1

Asymptotes at -3*π/2, *-*π/2, π/2, 3π/2*

One cycle occurs between -*π/2* and *π/2*
