Answer 2

Answer:

Step-by-step explanation:

sin ^2 30 + cos ^2 60 + tan ^2 45 + sec ^2 60 - cosec ^2 30

Sin 30 = 1/2 ; sin ^2 30 = 1/4

Cos 60 = 1/2 ; cos ^2 60 = 1/4

Tan 45 = 1 ; tan ^2 45 = 1

Sec 60 = 2 ; sec ^2 60 = 4

Cosec 30 = 2 ; cosec ^2 30 = 4

Therefore , it is equal to 1/4 + 1/4 + 1 + 4 - 4

= 6/4 = 3/2
