Question

sin30+tan45-cosec60/cot45+cod60-sec30

Answer 1

hi, First of all, we know that,

→ sin 30 = 1/2

→ tan 45 = 1

→ cosec 60 = 2/√3

→ cot 45 = 1

→ cos 60 = 1/2

→ sec 30 = 2/√3

Correction : You have written cod60 . It is wrong. It will be cos60.

→ Now, coming to answer your question

Given us,

sin 30 + tan 45 - cosec 60 / cot 45 + cos 60 - sec 30

= 1/2 + 1 - 2/√3 / 1 + 1/2 - 2/√3

= 3/2 - 2/√3 / 3/2 - 2/√3

= 3√3 - 4 / 3√3 - 4

= 0

Answer is 0
