To further justify the Cofunction Theorem, use your calculator to find a value for each pair of trigonometric functions below. In each case, the trigonometric functions are cofunctions of one another, and the angles are complementary angles. Round your answers to four places past the decimal point. ? sin 23°, cos 67° ?
A. sin 23° = 0.3907, cos 67° = -0.9205 B. sin 23° = -0.3907, cos 67° = 0.9205 C. sin 23° = 0.3977, cos 67° = 0.9135 D. sin 23° = 0.3907, cos 67° = 0.3907 E. sin 23° = 0.3857, cos 67° = 0.9205
