Prove the identity (sin6x)/(1+cos6x)=tan3x.
Vikentia [17]
Use double angle identity
sin(2x) = 2 sin x cos x \\  \\ cos(2x) = 2cos^2 x - 1

We can relate '6x' to '3x' in the same way since 6 is 2*3.
sin(6x) = 2 sin (3x) cos (3x) \\ \\ cos(6x) = 2cos^2 (3x) - 1

Now sub into left side of identity. Simplify until it equals right side.
\frac{2 sin(3x) cos(3x)}{1+(2cos^2 (3x) -1)} = \frac{2 sin(3x) cos(3x)}{2cos^2 (3x) } = \frac{sin(3x)}{cos(3x)} = tan (3x)

EleoNora [17]

Convert into decimal:

-3/10 = -0.3

-4/15 = -0.2667

-2/5 = -0.4

-0.4 < -0.3 < -0.267

-2/5 < -3/10 < -4/15
