Course 3
... To solve multi-step equations with variables on both sides, first combine like terms and clear fractions. Then add or subtract variable terms to both sides so that the variable occurs on only one side of the equation. Then use properties of equality to isolate the variable. ...

5.4 Trigonometric Functions of General Angles
... First we need to draw the triangle like we did the previous section. This time we are told 180 < θ < 270 , which means we need to draw the triangle in the third quadrant. Our fraction is negative. That means that either 1 or 4 must be negative when we put this in our drawing. The hypotenuse is NEVER ...
