WebDec 12, 2024 · Example 6.5.1: Use Double-Angle Formulas to Evaluate a Trigonometric Expression Given that tan θ = − 3 4 and θ is in quadrant II, find the following: a. sin(2θ) b. cos(2θ) c. tan(2θ) Solution If we draw a triangle to reflect the information given, we can find the values needed to solve the problems on the image. WebJan 16, 2024 · Half-Angle Formula for Tan Derivation We know that tan x = sin x / cos x such that, tan (x/2) = sin (x/2) / cos (x/2) Putting the values of half angle for sin and cos. We get, tan (x/2) = ± [ (√ (1 – cosy)/2 ) / (√ (1+ cosy)/2 )] tan (x/2) = ± [√ (1 – cosy)/ (1+ cosy) ] Rationalising the denominator
WebApr 2, 2024 · Half-angle formulas are used to find the exact value of trigonometric ratios for angles such as 22.5° (half the standard 45° angle), 15° (half the standard 30° angle), and so on. From the table of trigonometric functions, know the values of trigonometric functions (sin, cos, tan, cot, sec, cosec) for angles such as 0°, 30°, 45°, 60°, 90°.

WebIn this case, x 4 = 1 2 × x 2. Therefore, this is the formula for the cosine of half of the half angle. Now, let y = 2 x. Then, replace all of the x terms in the equation for the cosine of a half-angle with y 2. The new equation reads: c o s ( y 2 2) = c o s y 2 + 1 2. Then, use the original half angle formula and the fact that y 2 2 = x 4 to ...
