prove 5*2=5+5

Solution

prove

5 \cdot 2 = 5 + 5

True

Solution steps

5 \cdot 2 = 5 + 5

Manipulating left side

52

Simplify

= 10

Manipulating right side

5 + 5

Simplify

= 10

We showed that the two sides could take the same form

\Rightarrow True

- cot (x) + sec (x) csc (x) = tan (x)

cos^{2} (x) = cos^{2} (\frac{x}{2}) - sin^{2} (\frac{x}{2})

\frac{cos ( b )}{sin ( b )} = \frac{1}{tan ( b )}

\frac{cos ( θ ) csc ( θ )}{cot ^{2} ( θ )} = tan (θ)

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