## Homework Statement

So i'm following along with my physics book and I get to the point where

Mg * abs(sin(θ) - cos(θ)) <= μMg * (cos(θ) + sin(θ)

Next they say: If tan(θ) >= 1 then

sin(θ) - cos(θ) <= μ(cos(θ) + sin(θ)) => tan(θ) <= (1+μ) / (1-μ)

## Homework Equations

## The Attempt at a Solution

How do I go from sin(θ) - cos(θ) <= μ(cos(θ) + sin(θ)) to tan(θ) <= (1+μ) / (1-μ)?

Could someone walk me through this or at least get me started? Thanks
