(cos45^(@))/(sin30^(@)+cosec30^(@))

Evaluate the following : (cos45^(@))/(sec30^(@)+cosec30^(@))

Find the value of following expressions : (i) sec^(2)60^(@)cos^(2)45^(@)-cosec^(2)30^(@) (ii) (tan45^(@)cot^(2)60^(@)+tan^(2)30^(@)cot45^(@))/(sin30^(@)+cos60^(@))

Evaluate : (cos 45^(@))/(sec30^(@)+"cosec "30^(@))

What is the value of (sin 45^(@))/(sec 30^(@)+ "cosec" 30^(@))?

Evaulate : (tan45^(@))/("cosec "30^(@))+(sec60^(@))/(cot45^(@))-(2sin90^(@))/(cos0^(@)) .

Find the value of the following: (sin90^(@)+cos60^(@)+cos45^(@))xx(sin30^(@)+cos0^(@)-cos45^(@))

Evaluate The following : (cos 45^@)/(sec 30^@+cosec 30^@)

Find the value of : (tan45^(@))/(cosec30^(@))+(sec60^(@))/(cot45^(@))-(5sin90^(@))/(2cos0^(@))

Simplify cos45^@/(sec30^@+cosec30^@)
