Use a calculator to find tan of 62.5 degrees to four decimal places.
00:00:09.120 --> 00:00:22.920
Typing tan of 62.5 into our calculator gives us an answer of 1.920982127.
00:00:23.280 --> 00:00:27.240
We’re asked to round our answer to four decimal places.
00:00:27.720 --> 00:00:32.160
Therefore, the key number is the eight after the dotted line.
00:00:32.640 --> 00:00:37.280
As eight is bigger than five, we need to round up.
00:00:37.560 --> 00:00:44.960
Rounding up gives us an answer of 1.9210.
00:00:45.400 --> 00:00:48.720
We have increased the nine by one to give us 10.
00:00:49.040 --> 00:01:03.120
Therefore, tan of 62.5 is equal to 1.9210, to four decimal places.
