If and are positive real numbers and does not equal , then is equivalentto . Step 3 Create equivalentexpressionsin the equationthat all have equal bases. Step 4 WebExample 1: Using the value of tan 81°, solve: (sec² (81°) - 1). Solution: We know, (sec² (81°) - 1) = (tan² (81°)) = 39.8635 ⇒ (sec² (81°) - 1) = 39.8635 Example 2: Find the value of tan 81° if cot 81° is 0.1583. Solution: Since, tan 81° = 1/cot 81° ⇒ tan 81° = 1/0.1583 = 6.3138 Example 3: Find the value of 5 tan (81°)/6 tan (99°). Solution:
