To graph the function y = (1/2)cos(x), follow these steps:
-
Determine the key points of the cosine function:
- The cosine function oscillates between -1 and 1.
- Its maximum value is 1, and its minimum value is -1.
- The period of the cosine function is 2π, meaning it repeats every 2π units.
-
Scale the cosine function vertically by a factor of 1/2. This means that the amplitude of the function will be 1/2 of its original amplitude.
-
Plot key points on the graph:
- Start with the maximum point at (0, 1/2).
- Move to the right by π/2 units, the function value becomes 0.
- Move to the right by another π/2 units, the function value becomes -1/2.
- Move to the right by another π/2 units, the function value returns to 0.
- Continue this pattern for the entire period of 2π.
-
Connect the points with a smooth curve. Since cosine is a smooth, continuous function, the graph should form a smooth wave.
-
Label the graph with appropriate axes labels and title if necessary.
Following these steps will result in the graph of y = (1/2)cos(x).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
