I'm having trouble trying to solve the problem csc x - csc x cos2 x = sin x. I'm having trouble trying to identify the identy even with a list of them sitting next to me.

Q: What do you mean by cofactor and also define the same?

A:

Q: 2 1 Cof (A) i A = (5 -2 9 -6 5 US I -1 3.

A: The given matrxi is:A=32153-29-65To find its cofactor

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

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

Q: S./2(sec²x – cos²?x – tan²x)sin5xcosxdx -

A:

Q: Verify the identity: cos2 x - sin2 x = 2 cos2 x - 1

A:

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

A:

Q: why is the inverse cos of -30/12 not possible? I understand how we get the other x values but this…

A: We know cosx≤1 for all real x.

Q: = 4 cos 3x – 3 sin 4x

A:

Q: Simplify cos(arctan-1) O no solution O-V2/2 -V2/2 O V2/2

A: Solve the following

Q: Find the value of cos 1- + 2 sin 1/2

A: value=?

Q: sin (30)cos (32) %3D

A: Topic = Trigonometry    using formulascos 2x = 1-2 sin2xcos 2x = 2 cos2x - 1

Q: Does cos (π/2 - x) = cos (x - π/2)? Explain with examples

A:

Q: Give the exact value of COS (-) + sin ( 3 V3 O1 2 2 O V2 O 1+v3

A: We need to find the exact value of the given trigonometric ratios.

Q: 1+cos4x 1. 1-cos4x -csc2xdx

A:

Q: first derivation cos^3 (3x)

A: differentiate the function using chain rule.

Q: Prove cos4x=8cos4x-8cos2x+1

A: To prove:- cos(4x)=8cos4(x)-8 cos2(x)+1

Q: Use the cofunction identities to select the correct answer which fills in the blank. cos(10x) = sin_…

A: We know that, sin(90°+x) = cos(x) sin(90°-x) = cos(x)

Fundamentals of Trigonometric Identities

Trigonometric Identities are the equalities that involve trigonometry functions and hold for all the values of variables given in the equation.
