Which of the following is not an identity? 1. tan x + cotx = secx cSC X II. cos2x = sinx(cscx + sin x) 1. sin²x x = cos x(secx - cos x) O II and III

Q: evaluate exactly cos-1(-3/2)

A: -3/2 lies outside the domain of the function. Hence we will have no solution

Q: sec(-0) cose 1-cos²0 csc20 CS

A:

Q: Verify the identity: (cos 4x - cos 2x)/(sin 2x - sin 4x) = tan 3x

A:

Q: 2 1 + cos2x can be simplified to: O sin²x O csc² x O cos²x O sec² x

A:

Q: Find given - cosx sinz

A:

Q: 9. Solve the equation for x if 0 < x < 27. 2 cos x + tan x - sec x = 0 VI

A: The correct option is option A. Use the trigonometric ratios and identities to rearrange the given…

Q: What is cosx+tanx over sinx

A:

Q: Verify the identity: csc x cos2 x + sin x = csc x.

A: the given identity is: cscx cos2x+sinx=cscx we have to verify the identity.
