I would try Khan Academy. He does very good explainations
Answer:
tita = 0 , 180, 270, 360. ( tita = 0 ≤ x ≤ 360).
Step-by-step explanation:
sin tita + sin ^2 tita = 0
sin tita( sin tita + 1) = 0
sin tita = 0, - 1.
For angles between 0 and 360 inclusive sin = 0 gives 0, 180 and 360 degrees. The angle whose sine is -1 is 270 degrees.
tita = 0 , 180, 270, 360.
Y = 0.75x - 6
If the line is parallel then the gradient is the same
Substitute in the values x = 4 and y = 5
5 = 0.75x4 +c
5 = 1 + c
c = 4
The equation of the line:
Y = 0.75x + 4
