prove csc^2(x)+tan^2(x)-1=tan^2(x)

prove

csc^{2} (x) + tan^{2} (x) - 1 = tan^{2} (x)

False

Solution steps

csc^{2} (x) + tan^{2} (x) - 1 = tan^{2} (x)

Show that the two sides are not equal

For

csc^{2} (x) + tan^{2} (x) - 1 = tan^{2} (x)

plug in

x = 1

csc^{2} (1) + tan^{2} (1) - 1 = 2.83780 \dots

csc^{2} (1) + tan^{2} (1) - 1

Refine to a decimal form

= 2.83780 \dots

tan^{2} (1) = 2.42551 \dots

tan^{2} (1)

Refine to a decimal form

= 2.42551 \dots

The two sides are not equal

\Rightarrow False
