Question

Calculate sin45°.cosec45° + cos45°.sec45° + tan45º.cot45°​

Answer 1

Step-by-step explanation:

sin 45° = 1 /√2

cosec 45° = √2

sin 45° cosec45° = 1

cos 45° = 1/√2

sec45° =√2

cos 45° sec45° = 1

tan45° = cot 45° = 1

A.T.Q

sin 45° cosec45° + cos 45° sec45° + tan45° + cot 45° = 1+1+1 = 3

Therefore, sin 45° cosec45° + cos 45° sec45° + tan45° + cot45° = 3
