## ziqbal103 one year ago In which quadrant are the terminal arms of the angleslie when, (1).sin theta<0 and con theta >0 (2).cot theta>0 and cosec theta>0 (3).tan theta<0 and cos theta>0 (4).sec theta<0 and sin theta>0 (5).cot theta>0 and sin theta<0

|dw:1408605898608:dw| Remember this

ok All Students Take Calaulus

4. DanielK16

In quadrant I A stands for All, meaning all of the sins, cos, and tans are positive In quadrant II S stands for Sin, Meaning all but Sin becomes positive, the rest like cos and tan become negative In quadrant III T stands for Tan, Meaning all but Tan becomes positive.. In quadrant IV C stands for Cos, Meaning all but Cos is positive

Now, I'll walk you through first one and maybe the second to help you. Give a man afish feed him for day, teach a man to fish feed him for a lifetime: Am I riight? :)

6. ziqbal103

sure @DanielK16

7. DanielK16

1) Sin<0 Cos>0

8. DanielK16

Now we know that sin is less then 0 meaning it is negative and Cos is greater than 0 meaning it is a positive

9. DanielK16

What quadrant has Cos positive but sin negative?

10. ziqbal103

11. DanielK16

Correct! Now you just keep doing that and it's that easy!

12. DanielK16

Remember All Students Take Calc Each letter in the beginning stands for sin, cos or tan and even All. and whichever it is, that is the one that's positive

13. ziqbal103

next no.2 tell me @DanielK16 in which both are greater than zero ...

14. DanielK16

2) cotangent > 0 co-secant > 0 Just relax about the co's and just know that cotangent is just one over tan and co secant is one over sin Now with that said, we know Tan is greater than 0 meaning it's positive, and Sin is also likewise... We don't need to worry about Cos because in what quadrant does Tan and Sin both are positive?

15. DanielK16

Just mention my name when you get it all, I'll see if you got it all right :) I'mma see if I could help out other people. So, good luck and call me if you need me!

\(\large)thank~you~so~much\) @DanielK16

No problem :)
