WebThe identity 1 + cot2θ = csc2θ is found by rewriting the left side of the equation in terms of sine and cosine. Prove: 1 + cot2θ = csc2θ 1 + cot2θ = (1 + cos2θ sin2θ) Rewrite the left side. = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with the common denominator. = sin2θ + cos2θ sin2θ = 1 sin2θ = csc2θ WebRack. “Old school pool hall at its best.

WebJan 20, 2024 · 2 Answers Sorted by: 1 If x = tanC, and we have cos2A = cos2B, we need to minimize (x − sinA)2 + (1 x − cosA)2 = x2 + 1 x2 + 1 − 2(xsinA + cosA x) So, we need to maximize (xsinA + cosA x). It is known that maximum of αsinθ + βcosθ is √α2 + β2 , so it's maximum is √x2 + 1 x2, so our expression becomes x2 + 1 x2 − 2√x2 + 1 x2 + 1 = (√x2 + 1 …
