Class 11 Mathematics Chapter 3 Trigonometric Functions Worksheet with Answers
Question. Find the principal solutions of cosec 𝑥 = −2
Answer : ⇒ sin 𝑥 = −1/2
3rd quadrant, sin 𝑥 = sin (𝜋 +𝜋/6)
⇒ sin 𝑥 = sin (7𝜋/6)
4th quadrant, sin 𝑥 = sin (2𝜋 + 𝜋/6)
⇒ sin 𝑥 = sin (11𝜋/6)
⇒ 𝑥 = 7𝜋/6 and 𝑥 = 11𝜋/6 are the principal solutions
Question. Find the principal solutions of cosec 𝑥 = −2
Answer : cosec 𝑥
⇒ sin 𝑥 = −1/2
3rd quadrant, sin 𝑥 = sin (𝜋 +𝜋/6)
⇒ sin 𝑥 = sin (7𝜋/6)
4th quadrant, sin 𝑥 = sin (2𝜋 + 𝜋/6)
⇒ sin 𝑥 = sin (11𝜋/6)
⇒ 𝑥 = 7𝜋/6 and 𝑥 = 11𝜋/6 are the principal solutions
Question. Find the principal solutions of tan 𝑥 = √3
Answer : tan 𝑥 = √3
1st quadrant, tan 𝑥 = tan (𝜋/3)
⇒ 𝑥 = 𝜋/3 3rd quadrant, tan 𝑥 = tan (𝜋 +𝜋/3)
⇒ tan 𝑥 = tan (4𝜋/3)
∴ 𝑥 = 𝜋/3 and 𝑥 = 4𝜋/3 are the principal solutions
Question. Find the principal solutions of, sec 𝑥 = −1
Answer : sec 𝑥 = −1
⇒ cos 𝑥 = −1
2nd quadrant, cos 𝑥 = cos(𝜋 − 0)
⇒ 𝑥 = 𝜋
3rd quadrant, cos 𝑥 = cos(𝜋 + 0)
⇒ 𝑥 = 𝜋
∴ 𝑥 = 𝜋 is the principal solutions
