x	0^o	90^o	180^o	270^o	360^o
*sin x*	0	1	0	-1	0

2. y = kos x, 0^o≤ x ≤ 360^o

x	0^o	90^o	180^o	270^o	360^o
*kos x*	1	0	-1	0	1

3. y = tan x, 0^o≤ x ≤ 360^o

x	0^o	90^o	180^o	270^o	360^o
*tan* x	0	∞	0	∞	0

4. y = sin 2x, 0^o≤ 2x ≤ 360^o

5. y = kos 2x, 0^o≤ 2x ≤ 360^o

6. y = tan 2x, 0^o≤ 2x ≤ 360^o
