prove 9sec^2(0)tan(0)=12tan(0)

prove

9 sec^{2} (0) tan (0) = 12 tan (0)

True

Solution steps

9 sec^{2} (0) tan (0) = 12 tan (0)

Manipulating left side

9 sec^{2} (0) tan (0)

Simplify

9 sec^{2} (0) tan (0) : 0

= 0

Manipulating right side

12 tan (0)

Simplify

12 tan (0) : 0

= 0

We showed that the two sides could take the same form

\Rightarrow True

cot (x) - sec (x) csc (x) cos (2 x) = tan (x)

tan (x) = \frac{3}{7} = cos (x)

3 - 6 sin^{2} (x) = 3 sin (2 x)

sin (2 z) = sin (z) cos (z) + cos (z) sin (z)

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