Determine each tangent ratio to four decimal places using a calculator.

A) tan 74 degrees
B) tan 45 degrees
C) tan 60 degrees
D) tan 89 degrees

How do I figure this out !?

1. Steve

use your scientific calculator. if it's TI-like, just make sure the rad/deg display shows deg

press 74
press tan

If you don't have one, there are online scientific calculators

On some of them you press tan first.

2. Reiny

on your calculator , find a key labeled DRG
press until DEG shows

I will do C), you follow the same steps for the others

press:

tan
60
=

you should get 1.732.....

If this does not work,
then enter

60
tan
=

(the last method is used by a small number of manufacturers)
