संप्रत्यय:

व्युत्क्रम त्रिकोणमितीय फलन - मुख्य मान:

  • व्युत्क्रम ज्या फलन, जिसे sin⁻¹(x) लिखा जाता है, वह कोण देता है जिसका ज्या x है।
  • sin⁻¹(x) का परिसर (मुख्य मान शाखा) [−π/2, π/2] है।
  • इसलिए, sin⁻¹(x) केवल इस अंतराल में कोण देता है, भले ही समान ज्या मान कहीं और भी हो।
  • हमें sin⁻¹(1/√2) का मुख्य मान ज्ञात करना है।

 

गणना:

दिया गया है,

sin⁻¹(1/√2) = ?

⇒ 1/√2 = sin(π/4)

⇒ sin⁻¹(1/√2) = π/4

∴ sin⁻¹(1/√2) का मुख्य मान π/4 है।
