Given trigonometric ratio: tan 15 ∘. tan 15 ∘ can be expressed as, tan 15 ∘ = tan (45 ∘-30 ∘) We know that tan (A-B) = tan A-tan B 1 + tan A tan B. So by applying the above identity we get, tan (45 ∘-30 ∘) = tan 45 ∘-tan 30 ∘ 1 + tan 45 ∘ tan 30 ∘. As, tan 45 ∘ = 1, and tan 30 ∘ = 1 3. By substituting the values we get ...

The correct answer is 4. Given: tan 15° + cot 15°. To Prove: tan 15° + cot 15° = 4. Solution: tan 15° + cot 15°

5. Find the value of:i sin 75 ii tan 15∘

Find the value of tan 45 o + 2 cos 60 o – sec 60 o. Solution: From the trigonometry table, tan 45 o = 1, cos 60 o = ½ and sec 60 o = 2. Therefore, tan 45 o + 2 cos 60 o – sec 60 o = 1 + 2 × ½ – 2 = 1 + 1 – 2 = 0. Example 2: Find the value of sin 75 o. Solution: We can write, sin 75 o = sin (45 o + 30 o) = sin 45 o cos 30 o + cos 45 o ...
