The first thing to do is remove the coefficients of the side with the variable. This is done here by dividing by two, to give sin(2x) = 0.5. The next step is to remove the sine function; take the inverse sine of each side to give 2x = 30o (for degrees) or 2x = 0.5236 (for radians; equal to pi/6). Finally, remove the coefficient of x by dividing by 2 again. This gives 15o or 0.2618 (equal to pi/12). These are only the trivial solutions; all others can be found using predetermined formula.

Solve using the rule of 72 rate equals 4 percent years equals 18 fv equals 8000 solve for pv?
Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
