Question

Solve without using a calculator step by step plz
sin 30 degree csc 30 degree

Answer 1

@Hero

Answer 2

hint : csc30 = 1/sin30

Answer 3

to be honest i know that csc =1/sin and sin= 1/csc and now im stock

Answer 4

so, how do u simplify of
sin30 * 1/sin30 is .....

Answer 5

it is like u multiply 2 * 1/2, 3 * 1/3, 4 * 1/4, etc...

Answer 6

oooh

Answer 7

so, = ?

Answer 8

Do some reading about reciprocal trig functions at this site:

Answer 9

use the unit circle.

sin(30)= 1/2

Answer 10

Is this a new problem? -->
use the unit circle. sin(30)= 1/2

Answer 11

this is so confusing lol

Answer 12

it is like this
\[\sin(x)\times \csc(x)=\frac{\sin(x)}{\sin(x)}=1\]

Answer 13

the 30 degrees part is irrelevant
it is one no matter what

Answer 14

well can you please solve this in a sequential order so i can understand it

Answer 15

Have you studied any trigonometric identities yet?

Have you learned that sine of 30 degrees is 1/2 yet?

Have you learned the 30-60-90 theorem yet?

I ask because we need to know where you are in your study of trig.

Answer 16

i did first one

Answer 17

im now on inverse

Answer 18

I think maybe that drawing is what you want although I am not sure.

Answer 19

at the risk of repeating myself, the 30 degrees in the problem is irrelevant

Answer 20

@magepker728 wanted a unit circle demonstration.

Answer 21

i see with problems like this i need to think of the unit circle...
