skolas gadi bik aiz kalniem un algebra pieklibo vēl aizvien. vai kāds nevar, lūdzu, apskaidrot šo piemēru:
N= <G * { sin[(pi/2) - beta] } / { sin[(pi/2) + beta - alpha] } > = < G * { cos (beta) } / { cos [alpha - beta] } >
N= <G * { sin[(pi/2) - beta] } / { sin[(pi/2) + beta - alpha] } > = < G * { cos (beta) } / { cos [alpha - beta] } >
