Find the value of the following.
sin 75o 15’
Answer :
We write sin 75° 15’ = sin 75° 12’ + 3’.
The relevant part of the sine table is given below.
From the table, we have
Sin 75° 12’ = 0.9668
Mean difference for 3’ = 0.0002
We know that mean difference is to be added in the case of sine.
∴ sin75° 15’ = 0.9668 + 0.0002 = 0.9670
