Find the value of : " "(sin30^(@)-sin90^(@)+2cos0^(@))/(tan30^(@) times tan60^(@))

Find the value of : (sin30^(@)-sin90^(@)+2cos0^(@))/(tan30^(@) times tan60^(@))

(tan60^@)/(sin60^@+cos30^@)

Find the value of the following (i) tan 60^@ xx cos 30^@ (ii) sin 45^@ * cos 45^@ – sin^2 30^@ (iii) 2 sin 45^@* cos 45^@*tan 45^@ (iv) cos 30^@* cos 45^@ – sin 30^@* sin 45^@ (v) tan 30^@* sec 45^@ + tan 60^@* sec 30^@

Calculate : (tan60^(@)-tan30^(@))/(1+tan60^(@) tan30^(@))+cos60^(@) cos30^(@)+sin60^(@) sin 30^(@) .

Evaluate : (i) sin60^(@)*cos30^(@)-cos60^(@)*sin30^(@) (ii) tan30^(@)*cosec60^(@)+tan60^(@)*sec30^(@) .

(tan30^(@)cos ec60^(@)+tan60^(@)sec30^(@))=?

The value of ((1)/(3)cos30^(@))/((1)/(2)sin45^(@))+(tan60^(@))/(cos30^(@))=
