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. 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. 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)
