Question

Sec ²60 _ tan²60°
Sin 30° + Cos ²30​

Answer 1

Answer:

1) 4-3=1

2) 1/2+3/4=5/4

Answer 2

Answer :

1 .

sec 60° =2 and tan 60° =√3

putting value of sec 60° and tan 60°

SO,

we get ,

= (2) square -(√3) square

= 4 - 3

= 1

2.

sin 30°=1/2 and cos 30° =√3/2

putting value of sin 30 ° and cos 30°

SO.

we get,

= 1/2 +(√3/2) square

= 1/2+3/4

= 2+3/4

= 5/4
