Value of sin60^@//cos60^@

cos^(-1) sin (-60^(@))

If a sin45^(@).cos45^(@).tan60^(@)=tan^(2)45^(@)-cos60^(@) , then find the value of a .

Show that : (1-sin60^(@))/(cos60^(@))=2-sqrt3 .

(sec60)(cos60) =……………

If x sin 45^(@) cos 45^(@) tan60^(@)=tan^(2)45^(@) -cos60^(@) , then determine the value of x.

"(1) "sin60^(@)cos30^(@)+sin30^(@)cos60^(@)

(1-2[cos60^(@)-cos80^(@)])/(2sin10^(@)) = . .

Consider the following inequalities : 1. sin1^(@) lt cos 57^(@) 2. cos60^(@) gt sin 57^(@) Which of the above is/are correct?
