AS/A-Level Mathematics - Graph of sinθ, cosθ , tanθ

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

Sinθ°

Period: 

360° (2π)

Domain: 

x∝R

Range: 

-1 ≤ y ≤ 1

One cycle occurs between 0 and π

 Cosθ°

Period: 

360° (2π)

Domain: 

x∝R

Range: 

-1 ≤ y ≤ 1

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

Tanθ°

Period: 

180° (π)

Range: 

-1 ≤ y ≤ 1

Asymptotes at -3π/2, -π/2, π/2, 3π/2

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