WebWe know tan 38° = cot 52° ⇒ 8 tan 38°/cot 52° = 8 (tan 38°/tan 38°) = 8 (1) = 8 Example 2: Find the value of (2 sin (19°) cos (19°) sec (38°)). [Hint: Use tan 38° = 0.7813] Solution: Using sin 2a formula, 2 sin (19°) cos (19°) = sin (2 × 19°) = sin 38° ⇒ 2 sin (19°) cos (19°) sec (38°) = sin 38° sec 38° = sin 38°/cos 38° = tan 38° WebIn Indian astronomy, the study of trigonometric functions flourished in the Gupta period, especially due to Aryabhata, who discovered the sine function.
