Answer:
Refer to the attachments for the graphs of the given trigonometric functions.
Explanation:
Question 1

To sketch the graph of y = sin(x), draw a sinusoidal wave that oscillates between y = -1 and y = 1, and passes through the origin.
- The graph is continuous and repeats its behavior every 360°.
- The minimum value of the graph is -1, which occurs at the troughs of the wave when x = 270° + 360°n (where n is an integer).
- The maximum value of the graph is 1, which occurs at the peaks of the wave when x = 90° + 360°n (where n is an integer).
- The x-intercepts occur at x = 180°n, where n is an integer.
- The y-intercept occurs at the origin (0, 0).
The graph of y = sin(x + 30°) is the parent function y = sin(x) shifted to the left by 30°. The effect of this shift is that the graph will start rising from a point 30° earlier compared to the standard sine wave. This means that:
- The minimum value of the graph is -1, which occurs at the troughs of the wave when x = 240° + 360°n (where n is an integer).
- The maximum value of the graph is 1, which occurs at the peaks of the wave when x = 60° + 360°n (where n is an integer).
- The x-intercepts occur at x = 150° + 180°n, where n is an integer.
- The y-intercept occurs at (0, 1/2).

Question 2

To sketch the graph of y = cos(x), draw a sinusoidal wave that oscillates between y = -1 and y = 1.
- The graph is continuous and repeats its behavior every 360°.
- The minimum value of the graph is -1, which occurs at the troughs of the wave when x = 180° + 360°n (where n is an integer).
- The maximum value of the graph is 1, which occurs at the peaks of the wave when x = 360°n (where n is an integer).
- The x-intercepts occur at x = 90° + 180°n, where n is an integer.
- The y-intercept occurs at (0, 1).
The graph of y = cos(x - 60°) is the parent function y = cos(x) shifted to the right by 60°. The effect of this shift is that the graph will start rising from a point 60° later compared to the standard cos wave. This means that:
- The minimum value of the graph is -1, which occurs at the troughs of the wave when x = 240° + 360°n (where n is an integer).
- The maximum value of the graph is 1, which occurs at the peaks of the wave when x = 60° + 360°n (where n is an integer).
- The x-intercepts occur at x = 150° + 180°n, where n is an integer.
- The y-intercept occurs at (0, 1/2).

Question 3

The tangent graph has a distinct shape that is quite different from the sine or cosine graphs. The tangent graph is a periodic function with repeating patterns, but its behavior is more complex due to the nature of the tangent function.
The graph of y = tan(x) has vertical asymptotes at 90° + 180°n, where n is an integer. These asymptotes are vertical lines that the curve gets infinitely close to as it approaches positive or negative infinity, but never touches.
- The graph repeats its behavior every 180°.
- The x-intercepts occur at x = 180°n, where n is an integer.
- The y-intercept occurs at the origin (0, 0).
The graph of y = tan(x - 45°) is the parent function y = tan(x) shifted to the right by 45°. The effect of this shift is:
- The vertical asymptotes are at 135° + 180°n
- The x-intercepts occur at x = 45° + 180°n, where n is an integer.
- The y-intercept occurs at (0, -1).
