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). mmx4 boss weaknessesWebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25.
