    Tension and Uniform Circular Motion (no r, ω, θ)

    1 - cos^2 = sin^2 ? 1 - sin^2 = cos^2 ? Ah, I understand. I don't actively think that, thought it may have come off that way. I'm revisiting math/science education (sadly, not in a classroom) for the first time in 7 years (on the math side) and 10 years (on the general science side). I never...

    Tension and Uniform Circular Motion (no r, ω, θ)

    a^2 + b^2 = c^2 ? I'm sorry, I don't think I quite get what you're asking. Can you elaborate?

    Tension and Uniform Circular Motion (no r, ω, θ)

    Whoops, that should have been sin^2(θ), and my problem being that it is not tanθ (nor tan^2(θ)), and not allowing me to solve for θ with known values. EDIT: Ah, sorry - It looks like your quote was didn't copy the formatting correctly.
