WebJan 2, 2024 · On the unit circle, the largest x-coordinate a point can have is 1 and the smallest x-coordinate a point can have is 1. Since the output of the cosine function is the x-coordinate of a point on the unit circle, the range of the cosine function is the closed interval \([-1, 1]\). That means \(-1 \leq \cos(t) \leq 1\) for any real number \(t\). c++ all syntax pdfWebPurpose: Sympathovagal imbalance is a common underlying disorder in hypertension and diabetes.
