Answer
Die funksie f(x)=anx is ongedeffinieer waar die noemer van die tangensfunksie nul is, wat voorkom by:\
x=90exto+kimes180extoextwaarkext′ngeheelgetalis\
In die gegewe interval [0exto;360exto] is die waardes x=90exto en x=270exto.
Step 2
5.2.2 $f(x) imes g(x) ext{ } 0$ waar $x ext{ }
e [90^ ext{o}; 180^ ext{o}]$

Answer
Die produk f(x)imesg(x) is groter as nul wanneer albei funksies positief of albei funksies negatief is.\
xexte[0exto;90exto] (wat nie in die interval is)\
xexte[90exto;135exto] of x=180exto\
x behoort aan die interval [90exto;135exto] of x=180exto.
