It may be defined based on a right triangle or unit circle, in an analogical way as the sine is defined: The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. Introduction to Trigonometric Identities and Equations; 7. Also equals 1/tan(θ) coterminal angles the angles that have the same initial side and share the terminal sides gradian defined as one hundredth of the right angle. cos (60°) = 0. Answer.mathwarehouse. 7.5° And use the formula cos(A+B) = cos A cos B - sin A sinB Q: Triangle PQR q = 14 yards; r = 28 yards; m
