Find the values of: cos 75° - Mathematics and Statistics
WebMar 1, 2024 · We have the answer: sin15∘cos75∘ +cos15∘sin75∘ = 1. Explanation: The expression given matches the pattern of the formula for sin(x + y). Recall that formula: sin(x + y) = sinxcosy +cosxsiny. Now write it in the reverse direction: sinxcosy +cosxsiny = sin(x +y). Now, if in the reverse direction of that formula, we let: x = 15∘ and y = 75∘; we get: WebApr 13, 2024 · About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ... how to swap out computers
