Because Tan α > 0, α is in the first or third quadrant, because cos α = - 3 / 5, so sin α = - 4 / 5, Tan α = 4 / 3

Given Tan α = - 2, find the value of 2 sin 2 power α - 2 sin α cos α + cos 2 power α,

2 sin 2 power α - 2 sin α cos α + cos 2 power α
=[2 sin 2 power α - 2 sin α cos α + cos 2 power α] / (COS 2 α + sin 2 α)
=The denominator of (2tan? α - 2tan α + 1) / (1 + tan? α) is divided by cos? α
=(2×4+2×2+1)/(1+4)
=13/5

The fourth power of Tan is 270 degrees?

The final edge of 270 ° is on the y-axis, defined as tangent
Tan 270 ° is meaningless,
So the fourth power of Tan 270 degrees doesn't make sense
