WebFeb 9, 2024 · tan 2 (α) + 1 = sec 2 (α), 1 + cot 2 (α) = csc 2 (α). 2 Extending the domain There are several approaches for extending the domain of the trigonometric functions so they are not restricted to angles between 0 and 90 ∘ . WebIf \(\cos α = \frac{4}{5}\) and tan α < 0, evaluate a) sin α and b) cot α. Solution. Because cosine > 0 and tangent < 0, angle α is in quadrant IV and the signs of the trigonometric functions should be for that quadrant (see Lesson 4-05). An identity relating cos α and sin α is a Pythagorean Identity.
WebNote that the three identities above all involve squaring and the number 1.You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.. We have additional identities related to the functional status of the trig ratios:
WebQuestion: Suppose an angle 𝛼 is drawn in standard position. In each case, use the information to determine what quadrant 𝛼 is in. (An angle is in standard position if it is drawn on the xy-plane with its vertex at the origin and its initial side is on the positive x-axis.) (a) csc(𝛼) < 0 and tan(𝛼) > 0. (Select all that apply.) WebApr 14, 2015 · Explanation: cosA = 5 13. sin2A = 1 − cos2a = 1 − 25 169 = 144 169. sinA = ± 12 13. There are 2 opposite values of sin A, because, when cos A = 5 13, the arc (angle) A could be either in Quadrant 1 or in Quadrant 4. There are also 2 opposite values for tan A. tanA = sinA cosA = ± ( 12 13)(13 5) = ± 12 5. Answer link.
