The Trigonometry Ratios of the angle θ in the triangle APM are defined as follows.

Opposite over Hypotenuse – Sin, Adjacent Over Hypotenuse – Cos, Opposite over Adjacent – Tan, Hypotenuse over Opposite – Cosec, Hypotenuse Over Adjacent – Sec and Adjacent over Opposite – Cotangent,
The ratios defined above are abbreviated as sin θ, cos θ, tan θ, cosec θ, sec θ and cot θ respectively. Note that the ratios cosec θ, sec θ and cot θ are respectively, the reciprocals of the ratios sin θ, cos θ and tan θ. So, the trigonometric ratios of an acute angle in a right triangle express the relationship between the angle and the length of its sides.
Opposite of Sin: Cosecant
Opposite of Cos: Secant
Opposite of Tan: Cotangent
Opposite of Cosecant: Sin
Opposite of Cotangent: Tan
Opposite of Secant: Cosecant

We already know about isosceles right angle triangle and right angle triangle with angles 30º, 60º and 90º.
<figure aria-describedby="caption-attachment-76384" id="attachment_76384">Can we find sin 30º or tan 60º or cos 45º etc. with the help of these triangles?
Does sin 0º or cos 0º exist?
