So, cos (phi) * cos (phi) - sin (phi) * sin (phi) = cos^2 (phi) - sin^2 (phi) What's interesting about this trig identity is that you can use it to calculate cos (phi) in terms of cos or sin, by applying the Pythagorean identity. black and decker cordless trimmer partsWebb7 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 for sin θ/2 and cos θ/2. dave and busters mottoWebb1 dec. 2024 · R=2; [THETA,PHI]=meshgrid (theta,phi); X2=R.*cos (THETA).*sin (PHI); Y2=R.*sin (THETA).*sin (PHI); Z2=R.*cos (PHI); mesh (X2,Y2,Z2) In this case , if you want to see how the surface changes with r, you can use subplot to plot more picture in one window: Theme.
