Created by StemPy LabWhy compare np.sin(a) ** 2 + np.cos(a) ** 2 with 1 using np.allclose and not ==?
← All Quizzes
← A check of an identity on three angles. What does this print? `import numpy as np; a = np.radians(np.array([10, 20, 30])); print(np.allclose(np.sin(a) ** 2 + np.cos(a) ** 2, 1))`The true sine of a sum and the false rule, side by side. What does this print? `import numpy as np; a, b = np.radians(25), np.radians(65); print(round(float(np.sin(a + b)), 2), round(float(np.sin(a) + np.sin(b)), 2))` →
