[Solved] Algebraic Solutions to Graphical Trig Problems? (mander.xyz)

I’ve been knocking out the trig problems in this section with minimal difficulty so far, but I’ve run straight into a brick wall on this “Algebraic” part. I’m asked to find sin(x)=0 between [0,2π). If I graphed the unit circle this would be a trivial exercise to show sin(θ)=0 when θ=0 or π....

What's the word or area of math for a subset within a larger set of paired objects are mixed in a rotated fashion and the number of moves it takes to match all the pairs in the total set partially dep (lemmy.ml)

I feel like this has to be a math/logic thing that has a name already and I wanna know what it’s called so I can look it up when I’m no longer extremely drunk....

Can anybody help me understand this question? (i.imgur.com)

So I’m gearing up to take a calculus 1 exam, and this question is on the sample test. My initial thought was that since we are looking for F(9), and F(x) is an antiderivative of f(x), I can just use the integral of the equation of f(x) at 9, which is f(x) = -2x/3 + 5, which, when integrated, becomes -x^2/3 + 5x + 2 (C = 2...
