تعريف مدى دالّة

مجموعة القيم للمتغيّر المتعلّق، التي بها تكون الدالّة معرّفة

جد القيمة الصغرى والعظمى بكل مقطع ووحّد النتائج

cos(x)+sin(x) مجال التعريف لـ: −∞ <x<∞

نقاط قصوى ومقاطع ذات إشارة ميل رتيبة: عظمى(π4 +2πn, √2), صغرى(5π4 +2πn, −√2)

Equation1 هو −∞ <x<∞ مدى الدالّة، لمجال التعريف لـ: −√2≤ f(x)≤ √2

وحّد أمداء كلّ المقاطع لمجا التعريف من أجل الحصول على المدى العام

−√2≤ f(x)≤ √2
