Question

The value of 1/sin30 - √3/cos30 is ​

Answer 1

=4

Step-by-step explanation:

1/sin 10° -3/ cos 10°

=2x(1/2sin 10-√3/2cos /10°)

=2x(sin30/sin10-cos30/cos10)

=2x(sin 30 cos 10 cos 30 sin 10) /sin 10

=2x sin (30-10) sin 10 cos 10

=2x2 xsin 10 cos 10/sin 10 cos 10

=4

Answer 2

Answer:

0

Step-by-step explanation:

1/(1/2) -$\sqrt 3$($\sqrt 3$/2)

= 2 - 2

=0
