Question

use the value of the trig func to evaluate the indicated functions.
sin (-t)= 3/8
(a) sin t
(b) csc t

Answer 1

\[\huge \color{green} {\sin(-x) = -sinx}\]

Answer 2

then what's sin t? :O

Answer 3

\[\huge \color{blue}{cosecx = \frac{1}{sinx}}\]

Answer 4

Just replace x with t and use the formula..

Answer 5

@dorkkk Do you need to understand anything more? Can I clear the mess for you?

Answer 6

\(\Rightarrow \sin (-t) = \Large{3 \over 8} \)

\(\Rightarrow -\sin(t) = \Large{3 \over 8}\)

\(\Rightarrow -(-\sin (t)) = \Large{-3 \over 8}\)

\(\Rightarrow\sin t = -\Large {3 \over 8} \)

Answer 7

@dorkkk Did you get it?

Answer 8

okay i looked at the table

Answer 9

what about csc t?

Answer 10

\(\csc \theta \Longrightarrow \text{Just flip the } \sin \theta \)

Answer 11

So if \(\sin t= -\Large{3 \over 8}\), then \(\csc t = -\Large{8 \over 3}\)

Answer 12

@dorkkk Get it? :)

Answer 13

ahh, ok. thank you :D

Answer 14

Thanks for solving the entire question on your own @ParthKohli ..

Answer 15

Is that sarcasm?

Answer 16

Oh, I apologize for solving this question. I was just explaining it to him.

Answer 17

Explaining??

By solving the entire??

Answer 18

If you really want to explain then you can take the other examples too..

Answer 19

Yes. I explained him and gave the answer because it was the first time he encountered such a question. I'd ask him next time if there is a similar question related to this.

Answer 20

Did he reply any of your questions earlier.??

When you asked him after solving the entire then he said thanks...

Did not you get that he only wanted the answer and not the solution??

Answer 21

Yes, I did. I'd be asking him next time, as I told you. Please don't start a fight here. Thanks.

Answer 22

You can take other examples too if you want to explain...
then you may say him to do the original on your own..

Answer 23

woah woah woah, i don;t want any arguments here and yes, it was the first time i encountered this question. i am a girl btw :P

Answer 24

No, I sensed that Dork is a quick learner. She answered something in the last question.

Answer 25

If you are girl, then it does not mean that you will not reply if someone asks you...

Answer 26

I know the feeling of how you are confused. Are all your doubts clear now, Dork?

Answer 27

im just clearing it up because pathkohli was referring to me as a him.

Answer 28

I have to admit — That name makes me crack every time I see it ;)

Answer 29

yes, im good now and done with precal hw! chapter aka trig functions is quite a difficult chapter

Answer 30

If her doubts are cleared then give her a new problem to solve @ParthKohli ..

Answer 31

chapter 4*

Answer 32

Dork, can you calculate what \(\csc 45 \) is?

Answer 33

And without using a calcuator @dorkkk ..

Answer 34

You may ask us how to do it, if you have any doubt.

Answer 35

Yes sure if you have doubt then let us know..@dorkkk

Answer 36

1/sin45? =√2

Answer 37

Yes. Correct.

Answer 38

cool! :) thank you for your help. good night,

Answer 39

You're welcome! Good night!
