A quadratic equation is of the form ax2 + bx + c = 0 where a ≠ 0. A quadratic equation can be solved by using the quadratic formula. You can also use Excel's Goal Seek feature to solve a quadratic equation.
Solving quadratic simultaneous equations algebraically by substitution is covered, with examples, in a separate lesson. Step-by-step guide: Quadratic simultaneous equations Simultaneous equations examples For each of the simultaneous equations examples below we have included a graphical representation. Step-...
Example 1: Solving Trig Equations in Radians Let's start with a simple example and solve {eq}2sin(\theta) = \sqrt(2) {/eq}. The first step is to isolate the trig function: {eq}sin(\theta) = \sqrt(2)/2 {/eq} Now, what angle has a y value of {eq}\sqrt(2)/2 {/eq}?
Thequadratic formulais one of the most ubiquitous formula in mathematics. It appears when you are solving all kind of geometric problems, such as when you are maximizing an area, given a fixed perimeter, or in numerous word problems.
