For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.

WebAbstract. Superoscillating functions are band-limited functions that can oscillate faster than their fastest Fourier component. These functions appear in various fields of science and technology, in particular they were discovered in quantum mechanics in the context of weak values introduced by Y. Aharonov and collaborators. The evolution ... WebMar 9, 2024 · See tutors like this. We can use the double angle cosine formula here: cos (2θ) = 1 - 2 (sinθ) 2. Since cosθ is 24/25, we can infer the length of the third side since 24,25 is part of a pythagorean triple of 7,24,25. So sinθ = -7/25 (negative because θ is in the fourth quadrant). So cos (2θ) = 1 - 2 (-7/25) 2 = 527/625.
