Trigonometry
- Pythagorean Theorem
- Pythagoras
was a Greek
mathematician
- His theorem
was: a² + b² = c²
- His theorem
was: a² + b² = c²
- Pythagoras

- Trigonometric
Functions
- Soh Cah Toa
- Cosine
- cos(θ) = A ÷ H
- θ = cos⁻¹(A ÷ H)
- θ = cos⁻¹(A ÷ H)
- cos(θ) = A ÷ H
- Tangent
- tan(θ) = O ÷ A
- θ = tan⁻¹(O ÷ A)
- θ = tan⁻¹(O ÷ A)
- tan(θ) = O ÷ A
- Sine
- sin(θ) = O ÷ H
- θ = sin⁻¹(O ÷ H)
- θ = sin⁻¹(O ÷ H)
- sin(θ) = O ÷ H
- Cosine
- O-Opposite
A-Adjacent
H-Hypotenuse
- H
- A
- O
- θ
- H
- These are used
to find the side
lengths and
angles of a right
angled triangle
- Soh Cah Toa
- Angles of Elevation
and Depression
- The angles of elevation and
depression can be used with the
trigonometric functions to work out
the height of an object and the
distance you are from the object
- Distance (y)
- y = z ÷ (tan(angle of elevation/depression))
- y = z ÷ (tan(angle of elevation/depression))
- Height (z)
- z = y x (tan(angle of elevation/depression))
- z = y x (tan(angle of elevation/depression))
- Distance (y)
- z
- y
- The angles of elevation and
depression can be used with the
trigonometric functions to work out
the height of an object and the
distance you are from the object
