Answer 3

I have to fill in a table that has empty cells. The table has cos(theta) tan(theta) csc(theta) sec(theta) cot(theta) sin(theta), theta in degrees, and theta in radians. The theta is the zero with a line crossing through it. Anyway, I have cos(theta) as 1 and I have to find the other values

Answer 6

That is my question. I need to know how to fill in the other cells given cos(theta) 1

Answer 7

Ok you know that \[\cos \theta = 1 \rightarrow \cos \theta = \cos 0^0 \rightarrow \theta = 0^0\] since \[\cos 0^0 =1 ( chek -from-the- table)\]
Now we can find other trigonometric ratios, like
\[\sin \theta = \sin 0^0 = 0\]

\[\tan \theta = \tan0^0 = \infty \]

\[\cot \theta = \cot 0^0 = 0\]

\[\sec \theta = \sec 0^0 = 1\]
\[cosec \theta = cosec 0^0 = \infty\]

Answer 8

So those are the values I have to put into the empty cells? What is theta in degrees and theta in radians?

Answer 9

@dpasingh

Answer 10

Yes

Answer 11

how do I know the theta in degrees and theta in radians @dpasingh ?

Answer 12

let \[\theta \] be angle in degrees so we write it as \[ \huge \theta ^0 \]
To convert an angle i degrees to radian we must multiply the given angle by \[\huge \frac{\pi}{180^0}\]

Answer 13

so what is theta in radians then?

Answer 14

@dpasingh

Answer 15

@washcaps yes...

Answer 16

I'm here

Answer 17

I don't know what to put in the empty cell of "theta in radians"

Answer 18

just post your question. Is this the above question?

Answer 19

yes it is the same question. it all started with cos(theta) 1

Answer 20

\[0^0 = 0^0 \times \frac {\pi}{180^0} = 0^c\]

Answer 21

ok… so I put 0 degrees in the cell that says theta in degrees?

Answer 22

for angle in0 radians there would be no change for the values of the table, means table would take the ame values.

Answer 23

Medal please

Answer 24

I will give you a medal. Just clarify my chart. It will be an attachment

Answer 25

@dpasingh

Answer 26

just view my attachment and see if it is correct

Answer 27

hey @surjithayer could you help?

Answer 28

1. write 0,1,2,3,4 from left to right for sin and from right to left for cos
2.divide each by 4
3.take the square root of each.
4.for tan ,divide sin by cos
