Trigonometry: Find sin (180°)

Why is cos(180 - theta) = -cos(theta) and sin(180 - theta) = sin(theta)?

Sin 180 degree minus theta || Sin 180 degree minus theta is equal to 😀😀#maths #shorts

prove sin(180 - theta) = sin theta

sin(180) | sin(pi) | value of sin(180) | value of sin(pi)

Proof : cos ( 𝛳 ) = cos ( -𝛳 ) & sin ( 𝛳 ) = sin (180 - 𝛳 )

why sin(180-θ) = sinθ, sin(270+θ) = -cosθ, sin(360-θ) = -sinθ | Trigonometric Ratios of Allied Angle
