WebAug 29, 2016 · For any real $\theta$ the maximum value of $$\cos^2(\cos\theta) + \sin^2(\sin\theta)$$. A. $1$ B. $1 + \sin^21$ C. $1 + \cos^21$ D. does not exist. I tried it by converting the whole expression into $\sin$ but getting nowhere with that. WebIf 2sin 2 θ - cos 2 θ = 2, then find the value of θ. Solution: It is given that. 2 sin 2 θ - cos 2 θ = 2. As sin 2 θ + cos 2 θ = 1. We get cos 2 θ = 1 - sin 2 θ. 2 sin 2 θ - (1 - sin 2 θ) = 2. By further simplification. 2 sin 2 θ - 1 + sin 2 θ = 2. 3 sin 2 θ = 3. Divide both sides by 3. sin 2 θ = 1. Taking square root on both sides. sin θ = 1. So we get southside indianapolis homes for sale

WebHow to find the maximum and minimum values of 2sinθ+ cosθ, and the corresponding values of θ. f (x) = 2sinx + cosx f ' (x) = 2cosx - sinx Putting f' (x) = 0 cos (x) =1/√5 This implies at cos (x)=1/√5 we have a Maxima/minima At cos (x) = 1/√5 sin (x)= 2/√5 2 *2/√5 + 1/√5 is a minima or Maxima of ... Determine the exact value of ... Webcontributed. De Moivre's theorem gives a formula for computing powers of complex numbers. We first gain some intuition for de Moivre's theorem by considering what happens when we multiply a complex number by itself. Recall that using the polar form, any complex number z=a+ib z = a+ ib can be represented as z = r ( \cos \theta + i \sin \theta ... teal and orange film
