prove 5-5+5-5-5-5+5-5+5+5-5=-5

prove

5 - 5 + 5 - 5 - 5 - 5 + 5 - 5 + 5 + 5 - 5 = - 5

True

Solution steps

5 - 5 + 5 - 5 - 5 - 5 + 5 - 5 + 5 + 5 - 5 = - 5

Manipulating left side

5 - 5 + 5 - 5 - 5 - 5 + 5 - 5 + 5 + 5 - 5

Simplify

= - 5

We showed that the two sides could take the same form

\Rightarrow True

p ro v e 1 + cos^{4} (x) - sin^{4} (x) = 2 cos^{2} (x)

p ro v e cot (x) - sec (x) csc (x) cos (2 x) = tan (x)

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

p ro v e \frac{( tan ( x ) cot ( x ) )}{cos ( x )} = sec (x)

p ro v e cot (\frac{t}{2}) = \frac{sin ( t )}{1 - cos ( t )}
