Question

• How does the value of sinA change as angle a increases and decreases?

Answer 1

I'm sorry, the question is unclear. As A increases and decreases?

Answer 2

fixed lol sorry

Answer 3

It increases as the angle increases and decreases as the angle decreases

Answer 4

thankyou

Answer 5

My pleasure :)

Answer 6

llol

Answer 7

Need anything else?

Answer 8

hmmm

Answer 9

When in doubt, plug in values from your unit circle.
sin(0)=0
sin(pi/6)=11/2
sin(pi/4)=sqrt(2)/2
and so on, as it increases, it gets larger

Answer 10

sin(pi/6)=1/2*

Answer 11

• How does the value of cosA change as angle a increases and decreases?

Answer 12

Do the same,
cos(0)=?
cos(pi/6)=?
cos(pi/4)=?
View the pattern and see :D

Answer 13

no lol sowwy

Answer 14

Ok lol,
cos(0)=1
cos(pi/6)=sqrt(3)/2
cos(pi/4)=sqrt(2)/2
cos(pi/3)=1/2

Can you see a pattern?

Answer 15

still no v~v

Answer 16

sqrt(3)/2 > sqrt(2)/2 > 1/2 ; Cos A decreases as A increases and vice versa

Answer 17

\[\frac{\sqrt{3}}{2}=0.866025\]
\[\frac{\sqrt{2}}{2}=0.707107\]
It gets smaller and smaller.

Answer 18

who is right v~v

Answer 19

We both said the same thing lol.
cos(A) decreases as A increases.

Answer 20

oh lol okayz :)

Answer 21

• What happens to the value of tanA as you increase angle A ?

Answer 22

Again we would use the same method.
tan(0)=0
tan(pi/6)=sqrt(3)/3
tan(pi/4)=1
tan(pi/3)=sqrt(3)

Answer 23

still dont understand it lolz

Answer 24

And sqrt(3)/3<1<sqrt(3), from which we can deduce that Tan A increases as a increases and vice versa

Answer 25

As 0<pi/6<pi/4<pi/3 and sqrt(3)/3<1<sqrt(3), tan A increases as A increases and vice versa

Answer 26

they both increase???

Answer 27

Perhaps this would help you visualize?

Answer 28

Think of it as "0<pi/6<pi/4<pi/3" being the different values of A and sqrt(3)/3<1<sqrt(3) being the corresponding values of tan A

Answer 29

so they both are rising

Answer 30

Yes, as the other one rises

Answer 31

If one would decrease, so would the other

Answer 32

:D • How do the reciprocal values change compared to the other functions?

Answer 33

Simply put, as they're the reciprocals of the other ratios, they just wortk the opposite way :)

Answer 34

csc is the reciprocal of sin, sec is the reciprocal of cos, and cot is the reciprocal of tangent

Answer 35

lol okay :)

Answer 36

• Which values are always less than 1

Answer 37

What do you mean?

Answer 38

thts all it says

Answer 39

hmm

Answer 40

That's kinda weird

Answer 41

I agree, it's a bit unclear
