5 strategies you can use to solve TRIG IDENTITIES - Medium

WebThe hyperbolic functions pop up in trigonometry when you start defining the trig functions for complex arguments. For example, sin z = sinh (i*z) / i = - i*sinh (i*z). Fun fact: any chain or string that is attached from its endpoints forms a catenary, not a parabola. A catenary is of the form y = a * cosh (x/a). Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2.
