Ad-free Triangle Solver 6.3.1
If you know two angles and one side of a triangle, quickly andeasily calculate the rest. Also handles cases where you know twosides and one angle, or three sides and no angles. This is a trulyfree app -- no ad network! (It does have info on our Free GraphingCalculator. But it won't pop-up or annoy; only appears if you askfor it.)
Special Relativity 1.0
Special Relativity is a theory that can be derived fromtwofundamental principles. If you have a good understandingofalgebra, including matrices and linear transformations, thisappcan show you how. Topics covered -- First steps: • The constancyofthe speed of light (Experimental fact, leading to . . .) •TheIsotropy of Space (Fundamental principle #1) • The PrincipleofRelativity (Fundamental principle #2) • Seconds as a unitofdistance • World lines • Spacetime diagrams1+1-dimensionalSpacetime -- ideas and derivations: • The LorentzTransformation •Thought experiments with light and a mirror,leading to . . . •Derivation of the Lorentz Transformation • TheLorentz Boost • TheInverse Lorentz Transformation 1+1-dimensionalSpacetime -- more: •Spacetime intervals -- timelike, lightlike, andspacelike • Timedilation and Lorentz Contraction • Why one can'tdefine"Simultaneous events" when at different locations • Thefundamentalproblem with faster-than-light travel • Addingvelocities • TheSpacetime Invariant Additional space dimensions: •Perpendiculardistances • Perpendicular velocities Relativisticredshift •Derivation Mass and energy: • Rest mass and relativisticmass •Calculating relativistic mass • One derivation of E=mc² Theappcontains drawings wherever they are helpful for understanding--over 20 in total.
