NOTABLE POINTS IN Mathematics

The image above shows a right angled triangle. The angle of the above __right triangle__ is denoted as θ

Hypotenuse is always the longest side of the triangle.

Opposite is the side opposite the angle (θ)

Adjacent is the shorter side next to the angle (θ)

Each of Sin θ

,cosθand tanθare the ratio of sides of the right triangle. They are calculated by using the formula (margic word)sohcahtoa:

soh

Sin θ = Opposite/Hypotenuse

cah

Cos

θ = Adjacent/Hypotenuse

toa

Tan

θ = Opposite/Adjacent
