Description

Graph of y = cos x

Consider the graph of y = cos x for x between 0° and 360°. The graph starts at y = 1 when x = 0°, decreases to y = 0 at 90°, reaches y = -1 at 180°, returns to y = 0 at 270°, and back to y = 1 at 360°.

  1. a

    Calculate Find all values of x between 0° and 360° that satisfy the equation 2 cos x + 1 = 0.

    Aim for approximately 3 distinct marking points.
