WebNov 9, 2015 · Explanation: Call tan (112.5) = tan x. tan 2x = tan (225) = tan (45 + 180) = tan 45 = 1 Apply the trig identity: tan2x = 2tanx 1 − tan2x, we get: 1 = 2tanx 1 − tan2x 1 − tan2x = 2tanx. Solve the quadratic equation: tan2x +2tanx − 1 = 0 D = d2 = b2 − 4ac = 4 + 4 = 8 --> d = ± 2√2 Ther3 are 2 real roots: tanx = − 2 2 ± 2 √2 2 = − 1 ± √2. WebFeb 2, 2024 · This means that our half-angle is in the first quadrant (because it's between 0 and 90 degrees). This further translates to the sine, cosine, and tangent being positive. …

Use an appropriate Half-Angle Formula to find the exact valu

WebSolution Because 112.5° = 225° /2, we use the half-angle formula for cos α/2 with α = 225°. What sign should we use when we apply the formula? Because 112.5° lies in quadrant II, where only the sine and cosecant are positive, cos 112.5° < 0. Thus, we use the - sign in the half-angle formula. Example 66 Verify the identity: 1 cos2 tan ...
