1. ### Straight Line equation in 4th quadrant of cartesian coordinate system

Hi all, Thanks for the attention. I want to know the staight line equation for 4th quadrant of cartesian coordinate system. Also i need to find out the slope of the straight line and Y intercept or X intercept constant, which ever is applicable to the staight line equation. Thanks, drv

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 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.

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...
5. ### Which quadrant is 3370 in?

I used an online calculator to tell me that 3370 is in quadrant II, but how do I calculate that using my own knowledge or a hand-held calculator?
6. ### X Terminates in What Quadrant?

If (sec x - 2)(2 sec x - 1) = 0 , then x terminates in: a) Quadrants I and II, only b) Quadrants I and IV, only c) Quadrants I, II, III, and IV d) Quadrant I, only
7. ### 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?

9. ### Pre-Calc : Difference Quadrant help!

Ok, So I got two problems I have no clue how to do or finish the first I got far on.... First f(x) = 1/x+7 f(x+h) = 1/(x+h)+7 My work... [ 1/(x+h)+7 ] - [ 1/x+7 ] _____________________ h/1 Skip few steps.... Then 1(x+7) - (x+h)+7 / h [(x+h)+7](x+70 Dont know where...
