4 Given the following grid, how would you define z equals sin left parenthesis x right parenthesis to the power of 10 plus cos left parenthesis 10 plus x y right parenthesis cos left parenthesis x right parenthesis z = np.sin(x) * 10 + np.cos(10 + x*y) * np.cos(x) z = np.sin(x)**10 + np.cos(10 + x*y) * np.cos(x) z = np.sin(x**10) + np.cos(10 + x*y * np.cos(x)) z = np.sin(x)**10 + np.cos(x) * np.sin(10 + x*y)
