Dobrý deň,
Potreboval by som pomoc s nasledujúcou úlohou:
V trojuholníku PQR na strane PQ vyberieme bod S tak, že kružnica prechádzajúca bodmi PRS sa dotýka strany QR. Ďalej poznáme nasledovné dĺžky úsečiek: |PR| = 9 cm, |QR| = 120 mm (12cm) a |RS| = 0,6 dm (6cm). Vypočítajte vzdialenosť bodu S od bodu P.
Vopred ďakujem za odpoveď :)
Nech je daná kocka ABCDEFGH v KSS v E3 tak, že A = 0, B patrí x+, D patrí y+, E patrí z+ a /AB/ = a. Vypočítajte súradnice všetkých vrcholov tejto kocky v KSS, CSS a v SSS
Nech C = [3; 7], D = [– 5; 7] a 1F = [– 1; 4] sú vrcholy a ohnisko elipsy. Napíšte implicitnú a parametrické rovnice tejto elipsy, rovnice osí, hodnoty parametrov a, b, e a súradnice zvyšných…
