prove 1-cot(x)=1

Solution

prove

1 - cot (x) = 1

False

Solution steps

1 - cot (x) = 1

Show that the two sides are not equal

For

1 - cot (x) = 1

plug in

x = 1

1 - cot (1) = 0.35790 \dots

1 - cot (1)

Refine to a decimal form

= 0.35790 \dots

The two sides are not equal

\Rightarrow False

cot (x) - csc (x) = - \frac{1}{cot ( x ) + csc ( x )}

cos (θ + 3 0^{\circ}) - sin (θ + 6 0^{\circ}) = - sin (θ)

\frac{tan ^{2} ( x )}{sec ( x )} = sin (tan (x))

sin^{2} (0) = 2 - 2 cos (0)

cos (\frac{3 π}{8}) = \frac{2 - 2}{2}
