6. 1 trigonometric functions of acute angles notes: sterling. Provide a generalization to each of the key terms listed in this section. Acute angles are angles whose measures are always greater than 0 and always less than 90 , which can also be written by the following inequality: Greek letter n ame alpha beta gamma theta phi. When it comes to labeling each side with respect to the proper angles, the hypotenuse is side that"s opposite of the right angle, which is created by the adjacent and opposite sides. Ratio sine cosine tangent cosecant secant cotangent sin cos tan csc sec cot. Whenever you let theta, which is , be an acute angle of any right triangle, which will explain the following functions: Equalivant sin(x) sin (x) = 1 csc(x) cos(x) cos (x) = 1 sec(x) tan(x) tan (x) = 1 cot(x) csc(x) csc (x) = 1 sin(x) sec(x) sec (x) = 1 cos(x) cot(x) cot (x) = 1 tan(x)
