Step-by-step explanation:
Here's the system graphed. Not sure what you meant by solution though, what are you trying to find?
Answer:
(sin x)^2*(sec x) is positive in QII
Step-by-step explanation:
(sin x)^2 is always 0 or positive. Here x lies in QII.
sec x is positive when the adjacent side is positive and negative when the adjacent side is negative. In QII the adjacent side is positive.
In summary, (sin x)^2*(sec x) is positive in QII
Answer:
Step-by-step explanation:
2x - 2 = x
Bringing like terms on one side
2x - x = 2
x = 2
Z / -4 < 2....multiply both sides by -4, cancelling out the -4 on the left. And dont forget to change the inequality sign because of multiplying by a negative.
z > 2 * -4
z > -8
