What is positive concavity?
Space and AstronomyConcavity relates to the rate of change of a function’s derivative. A function f is concave up (or upwards) where the derivative f′ is increasing. This is equivalent to the derivative of f′ , which is f′′f, start superscript, prime, prime, end superscript, being positive. How do you know if concavity is positive? This point
What is so unusual about Pluto’s moon?

What is a secant angle?
Space and AstronomyThe secant angle equals half the sum of the angular measure of the two arcs (for A inside the circle) or half their difference (for A outside the circle). In the case where one of the secants is tangent to the circle, A still lies outside the circle and the angle intercepts two arcs. How
