Using the unit circle find cos, tan, and sin of the triangle formed from (sqrt2/2, sqrt2/2) to the x-axis, if the opposite side is 5, and the hypotenuse is 10. Keep values exact. 

Sin45=5/10

Cos45=sqrt75/10
Tan45=5sqrt75/75

400

Solve the trigonometric equation given by

(2sin(x) - 1)(tan(x) - 1) = 0 for 0 ≤ x ≤ 2 pi

x = pi/6, 5pi/6, x = pi/4 and x = 5pi/4

A ship leaves an island and goes 15 miles west. Then it stops and travels 20 miles south. What bearing should the boat take to directly return back to the island?

N36.87*E

A car leaves city B at a bearing of N20*E and goes straight for 200mi. How many miles did he travel north and east?

North: 196.96 mi

East: 34.73 mi
