Question

Sin(2)30-tan(2)60+cosec(2)60+6sec(2)45/cosec90+cos60-tan(2)45

Answer 1

Step by step:

= ((1/2)^2-(√3)^2+(2/

√3)^2+6(√2)^2)

_______________

(1+1/2)-(1)^2

= 1/4-3+4/3+12

_______________

2+1/2-1

= -11/4+4/3+12

______________

1/2

= -33+16/12+12

________________

1/2

= -17+144/12

______________

1/2

=254/12

=127/6
