Cot² x - tan² x = 1 is not true for all the values of x, where x is a trigonometric angle.
What is a trigonometric angle?
Trigonometric angles are the ratios of trigonometric functions.
If we consider a right-angle triangle with an angle between base and hypotenuse is Ф then:
tan Ф = (height/base), and
cot Ф = 1/tan Ф = base/height
Given, Cot² x - tan² x = 1
This is not true for all the values of x. Here, x is a trigonometric angle.
If we take x = 45°, then: Cot² x - tan² x = (1)² - (1)² = 0.
Hence, the statement is not true for all the values of x.
