Question

without using trignometrical table evaluate the following..
cot30°/sec30° + cosec30°/tan45° - 2cos 0°/sin30° + cos² 45°​

Answer 1

Step-by-step explanation:

Cot 30° = 1/tan30° = 1/(1/√3)

Sec 30° = 1/Cos30° = 1/(√3/2)

Cosec 30° = 1/Sin30° = 1/(1/2)

Tan 45° = 1

Cos O° = 1

Sin 30° = 1/2

Cos 45° = 1

Substituting the values, (refer to the attached picture) answer is 0.

Hope my answer helps you..........
