निम्नलिखित को सर्वसमिकाओं की सहायता से सिद्ध कीजिए

RBSE Solutions For Class 10 Maths Chapter 7 प्रश्न 3.
cos2θ + cos2θ . cot2θ = cot2θ
हल:
L.H.S. = cos2θ + cos2θ . cot2θ
= cos2θ6(1 + cot2θ)
= cos2θ . cosec2θ [∵ 1 + cot2θ = cosec2θ]
\(=\cos ^{2} \theta \cdot \frac{1}{\sin ^{2} \theta} \quad\left[\because \csc \theta=\frac{1}{\sin \theta}\right]\)
\(=\frac{\cos ^{2} \theta}{\sin ^{2} \theta}=\cot ^{2} \theta\) = R.H.S
∴ L.H.S. = R.H.S. ( इतिसिद्धम् )

RBSE Class 10 Maths Chapter 7 Exercise 7.1 प्रश्न 4.
sec θ(1 – sin θ) (sec θ + tan θ) = 1

Exercise 7.1 Class 10 In Hindi RBSE

RBSE Solutions For Class 10 Maths Ex 7.1 प्रश्न 16.
sin6θ + cos6θ = 1 – 3 sin2θ cos2θ
हल:
L.H.S = sin6θ + cos6θ
= (sin2θ)3 + (cos2θ)3
= (sin2θ + cos2θ)[(sin2θ)2 + (cos2θ)2 – sin2θ cos2θ]
=(1) [sin4θ + cos4θ – sin2θ cos2θ]
= [(sin2θ)2 + (cos2θ)2 + 2 sin2θ cos2θ – 2 sin2θcos2θ – sin2θ cos2θ]
= [(sin2θ + cos2θ)2 – 3sin2θcos2θ]
= (1)2 – 3 sin2θcos2θ
= 1 – 3 sin2θ cos2θ = R.H.S
∴ L.H.S = R.H.S ( इतिसिद्धम् )

Class 10 RBSE Maths Chapter 7 प्रश्न 22.
sin8θ – cos8θ = (sin2θ – cos2θ) (1 – 2sin2θ cos2θ)
हल:
L.H.S. = sin8θ – cos8θ
= (sin4θ)2 – (cos4θ)2
= (sin4θ – cos4θ) (sin4θ + cos4θ)
= [(sin2θ)2 – (cos2θ)]2 (sin4θ + cos4θ)
= (sin2θ – cos2θ) (sin2θ + cos2θ) (sin4θ + cos4θ)
= (sin2θ – cos2θ) (sin4θ + cos4θ] [:: sin2θ+ cos2θ = 1]
= (sin2θ – cos2θ) [(sin2θ)2 + (cos2θ)2 + 2sin2θcos2θ– 2sin2θ cos2θ]
(2 sin2θ cos2θ उपर्युक्त मे जोड़ने व घटाने पर)
= (sin2θ – cos2θ) [(sin2θ + cos2θ)2 – 2 sin2θ cos2θ]
= (sin2θ – cos2θ) (1 – 2 sin2θ cos2θ)
= R.H.S.
∴ L.H.S. = R.H.S. ( इतिसिद्धम् )
