How to find cos 2 theta given sin theta - Math Index

Web28 apr. 2016 · sin 2θ = sin θ But we know a formula for sin 2θ = 2 sin θ cosθ Therefore we must solve 2 sin θ cosθ = sin θ. Rearrange & factor: (sin θ) (2 cos θ - 1) = 0. Using the Zero Product Property, your solutions are those which satisfy either of the following: (sin θ) = 0 OR (2 cos θ - 1)= 0. You can take it from here! Upvote • 1 Downvote Add comment WebBy letting θ=2A{\displaystyle \theta =2A}, we get that cos⁡θ=1−2sin2⁡θ2≈1−θ22{\textstyle \cos \theta =1-2\sin ^{2}{\frac {\theta }{2}}\approx 1-{\frac {\theta ^{2}}{2}}}. Algebraic[edit] The small-angle approximation for the sine function. The Maclaurin expansion (the Taylor expansion about 0) of the relevant trigonometric function is[5] Web7 aug. 2013 · tan²θ = sin²θ + cos²θ = 1 That is wrong. tan²θ = sin²θ/cos²θ. Secondly, the identity is tan²θ + 1 = sec²θ, not tan²θ - 1. Maybe this proof will be easier to follow: tan²θ + 1 = sin²θ/cos²θ + … greensoft throw pillows
