Pie!!!

[BrittneyMay16]

Solve each equation for 0 Equal too or less then Theta Equal too or less then 2Pie

1. Cos(Theta) = Square root 3 / 2
2. Sin(Theta) = 1 / 2
3. Tan(Theta) = Square root 3
4. Tan(Theta) = -3 / 4
5. Sin(Theta) = -1
6. Cos(Theta) = -1 / 4

Can you please show me how to figure them out!!!

Pie is for eating
Pi is for greek spellers and for math

You can get many of them from memorization. If you know a few important and common angles, you're closer. Do you know sine, cosine, and tangent for 0º, 30º, 45º, 60º, and 90º? Look them up and see how many you can get just from this list.
