Question

Intr-un triunghi MNP dreptunghic in M se stie ca MN = 6 si MP = 8 . Calculati NP , sin P , cos P , cos N tg P , ctg P si ctg N

Answer 1

 [tex]NP=\sqrt{6^2+8^2}=10\;;\\ sinP=6/8=3/4=0,750\;;\;;\\ cosP=8/6=4/3=1,333...\;;\\ cosN=6/10=0,600\;;\\ tgP=6/8=0,750\;;\\ ctgP=8/6=1,333...\;;\\ ctgN=6/8=0,750\;;[/tex]
