Understanding Half Angles
Half angle formulas are essential tools in trigonometry that help calculate trigonometric values for half of any given angle. These formulas are particularly useful in fields like engineering, physics, and advanced mathematics.
Key Formulas:
sin(θ/2) = ±√((1 - cos(θ))/2)
cos(θ/2) = ±√((1 + cos(θ))/2)
tan(θ/2) = ±√((1 - cos(θ))/(1 + cos(θ)))
