The graph of \(y = \sin{\theta}\) has a maximum value of 1 and a minimum ... 360^\circ \leq \theta \leq 360^\circ\) so there are four solutions. There is a line of symmetry at \(x = 90^\circ ...

The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) and a maximum turning ... points are the roots or solutions of the equation ...
