1. COMPRENDE. Representa en un plano cartesiano dos ángu los que sean coterminales al ángulo dado en cada punto. a. \( -\frac{\pi}{4} \) b. \( \frac{3 \pi}{2} \)

\( \cos ^ { r } x - \sin x = \frac { 1 } { r } \)

\( \left. \begin{array} { l } { g ( x ) = \sin x + \cos x - 1 } \\ { g ( x ) = \cos ( x ) - \sin ( x ) = 0 } \end{array} \right. \)
