prove-tan(t)-(cos(t))/(sin(t)-1)=sec(x)

prove

- tan (t) - \frac{cos ( t )}{sin ( t ) - 1} = sec (x)

False

Solution steps

- tan (t) - \frac{cos ( t )}{sin ( t ) - 1} = sec (x)

Show that the two sides are not equal

For

- tan (t) - \frac{cos ( t )}{sin ( t ) - 1} = sec (x)

plug in

t = 0

For

- tan (t) - \frac{cos ( t )}{sin ( t ) - 1} = sec (x)

plug in

x = 1

- tan (0) - \frac{cos ( 0 )}{sin ( 0 ) - 1} = 1

- tan (0) - \frac{cos ( 0 )}{sin ( 0 ) - 1}

Use the following trivial identity:

tan (0) = 0

tan (0)

= 0

= - 0 - \frac{1}{0 - 1}

Simplify

= 1

sec (1) = 1.85081 \dots

sec (1)

Refine to a decimal form

= 1.85081 \dots

The two sides are not equal

\Rightarrow False

p ro v e \frac{cot ( x )}{tan ( x ) sec ( x )} = csc (x) - 1

p ro v e cos (\frac{π}{2} - x) cot (x) = cos (x)

p ro v e 2 sin (9 π - x) = 2 sin (x)

p ro v e \frac{sec ( x )}{csc ^{2} ( x )} = sec (x) - cos (x)

p ro v e (1 - cos (x)) = cos (x) - 1
