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
