Question

Find the remaining trigonometric ratios:

tan(x)=2, 0 < x < pi/2

1. sin(x)= _____
2. csc(x)= _____
3. cos(x)= _____
4. sec(x)= _____

Answer 1

5. cot(x)= _____

1. sin(x)= √(1/5)
2. csc(x)= √(5)
3. cos(x)= √(4/5)
4. sec(x)= √(5/4)
5. cot(x)= 1/2

Answer 2

wrong again.

Answer 3

not quite ....

sinx = 2/√5 or 2√5/5
cscx = √5/2
cosx = 1/√5 or √5/5
secx = √5
cotx = 1/2
