Full solution

Q. Solve.\newline y=cos(x3π2)1 y=\cos \left(x-\frac{3 \pi}{2}\right)-1
  1. Understand Cosine Function Properties: To solve the problem, we need to understand the properties of the cosine function and how it is affected by transformations. The function y=cos(x3π2)1y = \cos(x - \frac{3\pi}{2}) - 1 involves a horizontal shift and a vertical shift of the basic cosine function y=cos(x)y = \cos(x).
  2. Horizontal and Vertical Shifts: The horizontal shift is given by the phase shift (3π)/2(3\pi)/2 to the right. This means that the cosine function, which normally has a maximum at x=0x = 0, will now have this maximum shifted to x=(3π)/2x = (3\pi)/2.
  3. Evaluate Function: The vertical shift is given by subtracting 11 from the cosine function. This means that the entire graph of the cosine function is shifted down by 11 unit.
  4. No Specific Value Provided: We can now evaluate the function at any value of xx. However, since the problem does not specify a particular value of xx, we cannot provide a numerical answer. Instead, we have described the transformation of the cosine function.
