Web This Unit Looks At Trigonometric Formulae Known As The Doubleangleformulae.
They are called this because they involve trigonometric functions of double angles, i.e. Sin(2θ) = 2sinθcosθ cos(2θ) = cos2θ − sin2θ = 1 − 2sin2θ = 2cos2θ − 1 tan(2θ) = 2tanθ 1 − tan2θ how to:. So, we have \textcolor{blue}{\sin (2a)} = 2\textcolor{blue}{\sin a}.
