Question

find the value of sec 510°​

Answer 1

Answer:

$\frac{2}{ \sqrt{3} }$

Step-by-step explanation:

Given, sec510∘

=sec(5×90∘+60∘)

Here n=5 is odd,

so sec changes to csc.

=cosec(60∘)

since 510∘

lies in second quadrant.

=

$\frac{2}{ \sqrt{3} }$

Answer 2

Answer:root 3/2

Step-by-step explanation:

Given, sec510∘

=sec(5×90∘+60∘)

Here n=5 is odd,

so sec changes to csc.

=cosec(60∘)

since 510∘

lies in second quadrant.
