3 DoubleAngle Formulas by M Bourne The doubleangle formulas can be quite useful when we need to simplify complicated trigonometric expressions later With these formulas, it is better to remember where they come from, rather than trying to remember the actual formulasThe period of the tan(2x) tan (2 x) function is π 2 π 2 so values will repeat every π 2 π 2 radians in both directions x = π 8 πn 2, 5π 8 πn 2 x = π 8 π n 2, 5 π 8 π n 2, for any integer n nFirst, notice that the formula for the sine of the halfangle involves not sine, but cosine of the full angle So we must first find the value of cos(A) To do this we use the Pythagorean identity sin 2 (A) cos 2 (A) = 1 In this case, we find cos 2 (A) = 1 − sin 2 (A) = 1 − (3/5) 2 = 1 − (9/25) = 16/25 The cosine itself will be plus

From this formula we can derive tan(2x) as tan(xx) So tan(2x)= 2tanx/1tanxtanx We can always go for the longer approch from sinx/cosx to derive this formulaThe functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions Their usual abbreviations are (), (), and (), respectively, where denotes the angle The parentheses around the argument of the functions are often omitted, eg, and , if an interpretation is unambiguously possible The sine of an angle is defined34 Given the equation 3x2 2x k 0, state the sum and product of the roots Algebra 2/Trigonometry – June '15 14 35 Determine which set of data given below has the stronger linear relationship between x and y

Solve the equation tan( 2 x) = 1 tan( x) ( x) I have tried putting u = t a n ( x), and t a n ( 2 x) = 2 u 1 − u 2 so that − u 3 u 2 3 u = 1, but I can't find any roots that would help me I have also tried using all the trigonometric identities I could think of but that hasn't helped me either, so I have a feeling that I shouldFor the tan function, the equation is tan θ 2 = ± 1 − cos θ 1 cos θ {\displaystyle \tan {\frac {\theta }{2}}=\pm \,{\sqrt {\frac {1\cos \theta }{1\cos \theta }}}} Then multiplying the numerator and denominator inside the square root by (1 cos θ) and using Pythagorean identities leads toLearn formula of tan(2x) or tan(2A) or tan(2θ) or tan(2α) identity with introduction and geometric proof to expand or simplify tan of double angle
