WebExplanation for the correct option: Step 1. Find the value of cos ( θ - ϕ) 2: Given, cos θ = 3 5 and cos ϕ = 4 5, where θ and ϕ are positive acute angles. Thus, sin θ = 4 5 and sin ϕ = 3 … WebMay 22, 2015 · As required, set A = θ 2 & cos θ = 3 5 thus we get. sin θ 2 = ± 1 − cos θ 2 sin θ 2 = ± 1 − 3 5 2 = ± 1 5. Now, as per given constraints of θ. 360 o < θ < 450 o 180 o < θ 2 < 225 o. Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle θ 2 lies in the III-quadrant where ...

WebMar 23, 2024 · Step-by-step explanation: cos theta = 3/5. cos theta = adjacent side/ hypotenuse. Let adjacent side = 3 and the hypotenuse = 5. csc theta = hypotenuse/ opposite side. We need to find the opposite side. We know that this is a right triangle, so we can use the Pythagorean theorem. (adj)^2 + (opp)^2 = (hyp)^2. 3^2 + (opp)^2 = 5^2. Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve … asiasat ku band lnb frequency

"WebIt is also true that cos (½π-x) = sin (x) and that cos (x- ½π) = sin (x) So, cos (½π-x) = cos (x- ½π) Sine and cosine are both periodic functions that are identical except for being shifted ½π radians out of phase. Thus, there are a number of ways you can shift them around to be in phase and therefore equal. " - Cos theta equals 3/5
