    Quadrant solutions

    2 sin 4x + sqrt3 = 0 Rewritten: 2 sin 4x = - sqrt3 sqrt3 can be a positive or negative number so there are solutions in all quadrants? My book says only the third and fourth. I don't need any further work done.

    Which Quadrant?

    Which quadrant do the following angles lie in: 1. (5pie) / (4) 2. (7pie) / (4) I think it has something to do with whether the angle is between 0 and pie/2 or between pie/2 and pie, but I'm not sure how to classify them.

    Which Quadrant?

    In which quadrant is P(x,y) located if xy < 0 and x + y < 0? MY WORK: For xy > 0, I figured that for this to be true, both x and y must be positive values. In other words, x and y cannot be 0 and negative. For x + y < 0, one of the variables must be bigger than the other and negative...

    Determine tanx if secx=(sqrt14)/2 and is in the second quadrant

    Can someone explain this to me please? How would I approach this because I am confused about the sqrt14 and when I did get tan, it was -0.098etc. or something with that.. if it's negative and decimals, can tanx be correct?
