Question

Which of the following equations are identities? Check all that apply.

Answer 1

Answer:

B. CSCX=  sinx  / 1

D. tanx= sin x  / COS x

Step-by-step explanation:

A. sec x=  1/cos(x)

CSC X  / 1 = sin(x)

B. CSCX

sinx  / 1  = csc(x)

C. tanx=   sin(x) / cos(x)

secx  = 1 / cos(x)

D. tanx=  sin(x) / cos (x)

sin (x)  / cos(x)
