Nov 20, 2016 Solution: θ = 1350 and θ = 3150 Explanation: tanθ +1 = 0 # :. tan theta = -1 ; tan (pi-45)= -1 and tan(2π− 45) = −1 ∴ θ = π −45 = 1350 and θ = 2π −45 = 360 − 45 = 3150 Solution: θ = 1350 and θ = 3150 [ans] Answer link

WebJun 1, 2024 · DOUBLE-ANGLE FORMULAS. The double-angle formulas are summarized as follows: sin(2θ) = 2sinθcosθ cos(2θ) = cos2θ − sin2θ = 1 − 2sin2θ = 2cos2θ − 1 tan(2θ) = 2tanθ 1 − tan2θ. How to: Given the tangent of an angle and the quadrant in which it is located, use the double-angle formulas to find the exact value. WebNov 2, 2024 · Use the De Moivre Theorem to show that $$\tan6\theta=\frac{6\tan\theta-20\tan^3\theta+6\tan^5\theta}{1-15\tan^2\theta+15\tan^4\theta-\tan^6\theta}$$ I got this question on my exam today and had no idea how to do it. There must be a connection to complex numbers since its the topic its connected to. mineham mortgage services

WebMar 29, 2024 · tan−1(1) = 45o or π 4. On the tan graph the point 1 is repeated but at a different angle so you add 180o to 45o since it is positive. You use the 'CAST' diagram: C- cosine is positive so you do 360o - angle ( angle you calculated) A- all are positive. S- sine is positive so you do 180o - angle. T- tan is positive so you do 180o + angle.
