`(cos0^(@)+sin90^(@))xx(tan30^(@)xxtan60^(@))` is:

(sin30^(@)-sin90^(@)+2cos0^(@))/(tan30^(@)tan60^(@))

Evaluate : (cos^(2)(45^(@) + theta)+ cos^(2) (45^(@) -theta))/(tan(60^(@) + theta) xx tan(30^(@) - theta))+(cot30^(@) + sin 90^(@))xx (tan60^(@) -sec0^(@))

Evaluate : (cos^(2)(45^(@) + theta)+ cos^(2) (45^(@) -theta))/(tan(60^(@) + theta) xx tan(30^(@) - theta))+(cot30^(@) + sin 90^(@))xx (tan60^(@) -sec0^(@))

cot60^(@)xxtan30^(@)= ?

The value of (tan15^(@)xxtan45^(@)xxtan60^(@)xxtan75^(@)) is

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

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

Show that : (i) (1-sin60^(@))/(cos60^(@))=(tan60^(@)-1)/(tan60^(@)+1) (ii) (cos30^(@)+sin60^(@))/(1+sin30^(@)+cos60^(@))=cos30^(@)

(sin60^(@)+sin30^(@))/(sin60^(@)-sin30^(@))=(tan60^(@)+tan45^(@))/(tan60^(@)-tan45^(@))
