حل من أجل θ (tan(theta)+1)(sec(theta)+1)=0 Mathway

WebExplanation: r = secθ ⇒ rcosθ = 1. Now, use the conversion formula ; x = rcosθ,y = rsinθ ... In trig substitutions, why favor sin, tan, sec, sinh, cosh, tanh over cos, cot, csc, etc? … WebIf sectheta = x + 1/4x , then the value of sectheta + tantheta is equal to.

trigonometry - The quadratic equation whose roots are $\sec^2\theta …

WebBeginning with $1+\sin \theta = \sqrt{3} \cos \theta$, we can use the identity $\sin^2 \theta + \cos^2 \theta = 1$ to obtain $$1+\sin \theta = \sqrt{3(1-\sin^2\theta)} \\ \Rightarrow 1 + 2\sin \theta + \sin^2 \theta = 3-3 \sin^2 \theta \\ \Rightarrow 4\sin^2 \theta + 2 \sin \theta - 2 = 0$$ Now you have an quadratic equation for $\sin \theta$ which you can solve by … WebWe can read trigonometric definitions right from the triangle as corresponding ratios of sides. Specifically, for angle θ, tan θ = y x, and sec θ = r x. We can now write, 1 + tan 2 θ = … WebUse sec 2 θ = tan 2 θ + 1. Then you have a quadratic in sec θ. – Simon S. Aug 5, 2015 at 19:58. I did that but I didn't notice it was a quadratic, thank you! – TheNewGuy. Aug 5, 2015 at 19:59. @SimonS thank you, I got the answer it was (rounding decimals to three places) 1.231 + 2 π k, 5.052 + 2 π k, π + 2 π k. – TheNewGuy. cincinnati museum center philanthropy
