Jamia says that because sine is an odd function, sin (theta / 2) is always negative if thetatheta is negative. that is, she says that for
negative values of, sin ( theta / 2) = −(-1 − cos(theta) / 2 . is she correct? explain how you know.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x′y′z′, with vertices x′(4, -2), y′(4, -3), and z′(1, -4). the type of transformation that triangle xyz undergoes is a . triangle x′y′z′ then undergoes a transformation to form triangle x′y′z′, with vertices x″(4, 2), y″(4, 3), and z″(1, 4). the type of transformation that triangle x′y′z′ undergoes is a .
