Hope this helps =) 10. prove: cos^2 theta/2= tan theta + sin theta/2 tan theta ... WebWe can read trigonometric definitions right from the triangle as corresponding ratios of sides. Specifically, for angle θ, tanθ = y x, and secθ = r x. We can now write, 1 + tan2θ = 1 + (y x)2 = 1 + y2 x2 = x2 + y2 x2 = r2 x2 = (r x)2 = sec2θ. Since tanθ = sinθ cosθ and secθ = 1 cosθ , ⇒ tan2θ + 1 = sec2θ Hence Proved. las vegas hotel rates tonight
