XVerify the identity. (7 points) cos 4u = cos22u - sin22u
Alexandra [31]

Answer:

cos 4u = co^s2 2u - sin^2 2u

Step-by-step explanation:

cos 4u = co^s2 2u - sin^2 2u

Let 4u = 2x

cos 2x = cos^2 x - sin^ 2 x

cos (x+x) = cos^2 x - sin^ 2 x

Using cos(x+y) = cos(x)cos(y) -sin(x)sin(y)

cos(x) cos(x)- sin(x) sin (x)= cos^2 x - sin^ 2 x

cos^2 (x) -sin^2 (x) =cos^2 x - sin^ 2 x

Since this is true

cos 2x = cos^2 x - sin^ 2 x

This is true

Substituting 4u back for 2x

cos 4u = co^s2 2u - sin^2 2u

This is true

Gina looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one
Mice21 [21]
The shape of the room is not a square.
Pythagorean Theorem: 17^2+17^2= 578, square root 578 and you'll get 24.04.
The length of the diagonal of the floor of the room in the plan should have been 24.04 in order to be a square.
