Question

find the values of the trigonometric functions. Round off results.
1) sin 36.0 degrees i get 1.70
2)sec 7.8 degrees i get 1.00

find for the given trigonometric functions. Round off results.
4) cotθ=14.4 i get 3.970

find the value of the indicated trgonometric functions.
5) find cscθ=0.1063 i get 9.41

are all these correct and did i round them to the correct significant digit?

Answer 1

@jim_thompson5910 can you check my short answers please

Answer 2

@SithsAndGiggles

Answer 3

hmmm check your calculator is in Degrees mode, assuming that was say sin(36 degrees)

Answer 4

is not 1.7 btw

Answer 5

ok so for the first is sin 36.0 i did 1/ sin*36

Answer 6

1/sin*36? what do you mean?

Answer 7

i'm thinking this is the function i should use

Answer 8

ohh you meant \(\bf sin^{-1}(36^o)\quad ?\\ \quad \\
btw \qquad sin^{-1}(\theta) \ne\cfrac{1}{sin(\theta)}\)

Answer 9

that would then give me 1.592

Answer 10

"find \(\color{red}{\text{the values}}\) of the trigonometric functions. Round off results."

Answer 11

the inverse functions are to get the angle, once you have the "value"

Answer 12

ok

Answer 15

yeah that's what i got .587

Answer 16

i don't know why i did scs
