Sine(sin) and Cosine(cos) are each a ratio of sides of a right angled triangle
The sin θ = opposite/hypotenuse
the cos θ = Adjacent / hypotenuse
In this scenario, the angle θ each ratio stays the same no matter how big or small the triangle is.
Calculators have sin, cos, and tan on them, to make it simple for you. Simply put in the point and press the button.
The value of cos pi - 1 = -0.540
The value of sin pi 0 = 0
The sin θ = opposite/hypotenuse
the cos θ = Adjacent / hypotenuse

The value of Cos pi= -1 and Sin pi=0.
As we know the period of cos is 2pi or 360° e.g. the cos start repeating after 2pi or 360°. The value of cos ranges from 1 (cos0°=1) that is also its maximum value to its minimum value -1 (cos180°=cos pi=-1). cos0°=1 cos90°=0 cos180°=-1 cos270°=0 and cos360°=1
The period of sin is also 2pi or 360° and its value repeats after 2pi or 360°. The range of sin is also 1 to -1 sin0°=0 sin90°=1 sin180°=0 sin270°=-1 and sin360°=0.
