What basic trigonometric identity would you use to verify that sinx + 1/ sinx = 1+ cscx

C)  We use csc = to verify.

Step-by-step explanation:

Given : = 1 +csc x.

To find : What basic trigonometric identity would you use to verify.

Solution : We have given that   = 1 +csc x.

To  verify we need to show left hand side equal to right hand side.

For right hand side

1 +csc x  

By csc = .

Plug the value  csc = .

1 +  .

Taking least common multiple

= left hand side.

We can see this is equal to left hand side

Hence , left hand side = right hand side.

Therefore, C)  We use csc = to verify.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

center= (-2,0)

radius= sqrt2/2
