Activity #6

If you don't have a calculator, the values can be obtained from a table of trigonometric functions, such as the one included at the end of this packet. Use the table to find the values for the following angles.

1.) cos 34⁰ =    2.) tan 56⁰ = 3.) sin 40⁰ =

4.) cos 40⁰ = 5.) tan 10⁰ = 6.) cos 90⁰ =

7.) tan 90⁰ =   8.) tan 45⁰ = 9.) sin 45⁰ =

10.) cos 45⁰ =

Now use the table to find the angle that matches each of the following trigonometric values.

1.) cos A = 0.4848 2.) sin A = 0.7771 3.) tan A = 0.2679

4.) sin A = 0.8660   5.) cos A = 0.9205       6.) tan A = 5.1446

7.) cos A = 0.0523 8.) sin A = 0.0523 9.) tan A = 1.0000

10.) sin A = 0.5299

If you don't have a calculator, the values can be obtained from a table of trigonometric functions, such as the one included at the end of this packet. Use the table to find the values for the following angles.
1.)	cos 34⁰ =	2.)	tan 56⁰ =	3.)	sin 40⁰ =
4.)	cos 40⁰ =	5.)	tan 10⁰ =	6.)	cos 90⁰ =
7.)	tan 90⁰ =	8.)	tan 45⁰ =	9.)	sin 45⁰ =
10.)	cos 45⁰ =

Now use the table to find the angle that matches each of the following trigonometric values.
1.)	cos A = 0.4848	2.)	sin A = 0.7771	3.)	tan A = 0.2679
4.)	sin A = 0.8660	5.)	cos A = 0.9205	6.)	tan A = 5.1446
7.)	cos A = 0.0523	8.)	sin A = 0.0523	9.)	tan A = 1.0000
10.)	sin A = 0.5299
