(1-sin(+sin(x))=1/1+tan(x^2) prove that the statement is an identity

(1-sin(x))(1+sin(x))=1/1+tan(x^2)

I think  the right side is  tan^2 x    ( the square of tan x)

Left side =  1 - sin^2 x

Right side = 1  / ( 1 + (sin^2 x / cos^2x))

= 1  /    (cos^2x + sin^2x) / cos^2 x

Now sin^2 x + cos^2 x = 1  so

this =  1  /   1 / cos^2x

= cos^2x  = 1 - sin^2 x  = Left side    - Proved

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
