Use the graph below to find an equation for the line L in terms of the variable x which may depend on the angle Q labeled below. (The angle Q is a parameter.)

L=f(x)=      (Your formula is a function of x that also depends on the value of the parameter Q.)

Solution

    slope intercept : y = mx +b

. y intercept = b = sin(Q)

slope = m = sin(Q) cos(Q)

y = [sin(Q) cos(Q)]•x + sin(Q)
