Answer:

(-∞,0)∪(0,∞)

Step-by-step explanation:

So we know that the domain is whatever X can be. We can do that by graphing the function. When we graph the function, you see that there is always an X value except at 1 point. That one point happens to be when x=0, and when x=0, the function also happens to be undefined (no number can be divided by 0). That is why the graph looks so weird. So, the answer would be

(-infinty,0) U (0, infinity)

fie abc un triunghi cu masura unghiului a de 90 de grade ab este 6 cm bc=10 si ca=8 calculati;sin b; tg b; sin c; tg c; cos b; c

lions [1.4K]

SinB = cosC = AC / BC = 8/10 = 4/5;
tgB = ctg C = AC/AB = 8/6 = 4/3, because we use T. Pitagora for calculating AB;
sinC = cosB = AB/ BC = 6/10 = 3/5;
tgC = ctgB = AB/ AC = 6/8 = 3/4.
