When do you use sine, cosine, and tangent, and when do you use their reciprocals of these also known as cosine, secant, and cotangent
Anyone please
this is like asking when do you use 2, and 3, and when do you use 1/3 and 1/2
Well can you explain
I'm confused
there are 10000000000000.............. different ways to use them
can you be more specific?
I know using a negative sine is when you are looking for an angle
I'm confused on this question whether to use cosine or secant
um, I think you may need to read about the unit circle and what sine and cosine are, negative sine does not imply you are looking for an angle.
what is the question?
The picture below shows a right triangle shaped charging stand for a gaming system. Which expression shows the length of side AB? 8 cosec 60° 8/cos60°
I know it's either one of those but am unsure
soh cah toa cos(x) = adjacent over hypotenuse so let so cos(60) = 8/AB so AB = 8/cos(60)
How is it not cosecant that's where I'm confused
ANYONE?
I don't know why it would be again soh cah toa cah implies cos = adjacent/hypot0nuse I have not said the word cosecant.....
a = b/c you are given a and b solve for c
I know but my original question was knowing when to use secant
when you don't want to write 1/cos
So I don't know which one to use
How would I know not to make it in hypotenuse over adjacent
1/cos(60) = sec(6) 1/sin(60) = csc(60)
you remember the rule
soh cah toa
What does it mean
|dw:1374821490128:dw| soh means sin(theta) = opposite / hypotenuse cah means cos(theta) = adjacent/hypotenuse toa means tan(theta) = opposite/adjacent
You are avoiding my original question
lol
ok when do you use the number 2?
What?
exactly
WHEN DO YOU USE SECANT!!!!!!!!!!!!!!
WHEN DO YOU USE 2!!!!!!!!!!!!!!!!!!!!!!!!
AND ALL OF THE OTHER RECIPROCALS
secant(x) = 1/cos(x)
that's all I can tell you
I know how to do it
Just want to know when
So in the future I will not need help
ok say you have something like cos(x) = 1/2 then 2 = 1/cos(x) maybe you don't like to write fractions so you write it as 2 = sec(x)
When you are solving an equation like the one I showed you above
if you don't understand that I don't know what to tell you.....and using all caps will not help. You are asking a VERY open ended question. Your question is similar to me asking you when do you use 2 one can use 2 in many situations...
again when ever you have 1/cos(x) you use it
so again
if you have 1/cos(x) write it as sec(x)
Never mind you were no help
But I will medal you for trying
listen you need to grow up, and learn to ask a question. Don't be ruse. I am taking my time to sit hear and try and explain something to you....
I don't need a medal
there 5billion different ways you would use secant in a trig question. Your question is to vague..............
Okay zzr0ck I learned that we solve using the reciprocal as well when you are solving a problem
Besides the course I am taking is Geometry
So it will be very basic trigonometry
one example |dw:1374821963632:dw| cos(x) = 2/4 so 4 = 2/cos(x) = 2sec(x)
Go back to my question then why is the other answer incorrect
because the answer is 8/cos(60) the other answer says 8csc(60) = 8/sin(60)
OOOOHHHHH
THANK YOU VERY MUCH
so the answer is 8/cos(60) you may also write this as 8sec(60)
Didn't see that
I'm very sorry for the trouble that I caused
Along with my fit
so your question, after all this time was does 8/cos(60) = 8cosecant(60)
Haha I guess so
