sin(θ+φ)=sin(θ)cos(φ)+sin(φ)cos(θ)sin(θ+φ)=sin(θ)cos(φ)+sin(φ)cos(θ) To obtain this formula, we can use a beautiful graphic proof: Starting from the light blue triangle, we can find the values of the sides of the two smaller triangles with angl...
Usingtrigonometric functions calculator, we can get the value of sin 1031.32°. Hence, sin 18 rad = 0.769214… We know that 1031.32° lies in the fourth quadrant, where sin is negative. Therefore, sin 18 rad = -0.769214… Also, we can represent the value ofsin 18 in fractionin the same...
