Question

What is the value of `sin37°34'` to four decimal places?

Answer 1

`sin37^@34'=0.6097`

Explanation:

There are two ways.

One - See tables of sine chart. In this against `37^@` you get `0',6',12',24',30',36',.....`. For `34'` pick `30'` and you get `0.6088`. Now add numbers given under `4'`, which is `9` and you get `sin37^@34'=0.6097`

Two - As one degree is `60` minutes, `34'=34/60=17/30=0.5667` and `37^@34'=37.5667^@`.

Now use degrees in scientific calculator to get `sin37.5667^@=0.60968~=0.6097`
