المسألة 1:
الدالة د(س)=قتا سد(س) = \text{قتا س} متصلة عند س=π4س = \frac{\pi}{4}.
دالة قتا سس هي 1جا س\frac{1}{\text{جا س}}. تكون الدالة غير متصلة عندما جا س=0\text{جا س} = 0.
عند س=π4س = \frac{\pi}{4}، جا(π4)=22≠0\text{جا}(\frac{\pi}{4}) = \frac{\sqrt{2}}{2} \neq 0.
إذن، الدالة متصلة عند س=π4س = \frac{\pi}{4}.
✅
