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

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

Evaluate (cos 45^(@))/(sec 30^(@) + cos 30^(@))

( cos 45^ @)/( sec 30^@ + cosec 30 ^@) = ?

Evaluate: (cos45)/(sec30+cosec30)

Evaluate the following (i) sin 60^@ cos30^@ + sin 30^@ cos 60^@ (ii) 2tan^2 45^@ + cos^2 30^@ - sin^2 60^@ (iii) (cos45^@)/(sec30^@ + c o s e c 30^@) (iv) (sin30^@ + tan45^@ - c o s e c 60^@ )/(sec30^@ + cos60^@ +cot45^@) (v) (5cos^2 60^@ + 4sec^2 30^@ - tan^2 45^@ )/ (sin^2 30^@ + cos^2 30^@ )

Evaluate the following (i) sin 60^@ cos30^@ + sin 30^@ cos 60^@ (ii) 2tan^2 45^@ + cos^2 30^@ - sin^2 60^@ (iii) (cos45^@)/(sec30^@ + c o s e c 30^@) (iv) (sin30^@ + tan45^@ - c o s e c 60^@ )/(sec30^@ + cos60^@ +cot45^@) (v) (5cos^2 60^@ + 4sec^2 30^@ - tan^2 45^@ )/ (sin^2 30^@ + cos^2 30^@ )

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

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

using trigonometric tables evaluate the following : (cot 30^(@))/(sec 30^(@)) + ("cosec 30"^(@))/(tan 45^(@)) - (2 cos 0^(@))/(sin 30^(@)) + cos^(2) 45^(@)
