The Deep Dive
Did you know that the cosine function is intimately related to the unit circle? When you draw a circle with radius 1, the x-coordinate of any point on the circle gives you the cosine of the angle formed with the positive x-axis. For an angle where
, you can visualize it by drawing the line representing that angle in the first quadrant, where the angle is indeed acute!
To find
, you can use the inverse cosine function. Simply input
into a scientific calculator to get
after rounding. Just remember to ensure your calculator is set to degrees, not radians, unless you’re up for a little conversion challenge!
