without using trignometric table. Evaluate<br />Cot 30°÷Sec 30°+Cosec 30°÷Tan 45°-2 Cos tita°÷Sin 30°+Cos^2 45°​

Answer 1

Step-by-step explanation:

Given Without using trignometric table. Evaluate Cot 30°÷Sec 30°+Cosec 30°÷Tan 45°-2 Cos tita°÷Sin 30°+Cos^2 45°

• Given cot 30 / sec30 + cosec 30 / tan 45 – 2 cos 0 / sin 30 + cos^2 45
•   So √3 / 2 / √3 + 2 / 1 – 2 (1) / 1/2 + (1/√2)^2
•    = 3/2 + 2 – 4 + 1/2  
•    = 3 + 4 – 8 + 1 / 2
•   = 0
