GEO. ANALÍTICA - AULA 128 - EQUAÇÃO REDUZIDA DA PARÁBOLA

#analyticgeometry #conics #parabola If a parabola has its directrix parallel to the x-axis and its concavity facing upwards, its reduced equation is (x - xo)² = 2p(y - yo) If a parabola has its directrix parallel to the x-axis and its concavity facing downwards, its reduced equation is (x - xo)² = -2p(y - yo) If a parabola has its directrix parallel to the y-axis and its concavity facing right, its reduced equation is (y - yo)² = 2p(x - xo) If a parabola has its directrix parallel to the y-axis and its concavity facing left, its reduced equation is (y - yo)² = -2p(x - xo)
