If 1^(@)=0.01745^(c), sqrt3=1.732, then sin 32 ^(@)~~....

If 1^(@)=0.01745 radians. Then the approximate value of tan46^(@) is

Without using tables, evaluate the following: 3 cos 68^(@) . "cosec" 22^(@) - (1)/(2) tan 43^(@) .tan 47^(@) .tan 12^(@).tan 60^(@).tan 78^(@) .

The value of (tan 47^(@) + tan 43^(@))/(1-tan 47^(@) tan 43^(@)) is

cos 61^(@) , it being given that sin 60^(@) = 0.86603 and 1^(@) = 0.01745 radian.

Find the value of tan4^(@).tan43^(@).tan47^(@).tan86^(@) .
