To calculate the amplitude, period in radians, phase shift in radians, vertical shift, and maximum and minimum values, we need to consider the general form of the sine and cosine functions:
1. Sine function: y = A*sin(B(x - C)) + D 2. Cosine function: y = A*cos(B(x - C)) + D
Where: - A is the amplitude - B is the period in radians (B = 2π / period) - C is the phase shift in radians - D is the vertical shift
For the sine function: - Amplitude = A - Period in radians = 2π / B - Phase shift in radians = C - Vertical shift = D - Maximum value = A + D - Minimum value = -A + D
For the cosine function: - Amplitude = A - Period in radians = 2π / B - Phase shift in radians = C - Vertical shift = D - Maximum value = A + D - Minimum value = -A + D
Now, let's consider an example: y = 2*sin(3(x - π/4)) + 1
For the sine function: - Amplitude = 2 - Period in radians = 2π / 3 ≈ 2.094 - Phase shift in radians = π/4 ≈ 0.785 - Vertical shift = 1 - Maximum value = 2 + 1 = 3 - Minimum value = -2 + 1 = -1
Now, let's draw the graphs of the sine and cosine functions with the given parameters.
