MathIsFun.com's Heron's Formula Follow the easy-to-understand instructions on how to use Heron's Formula to find the area of a triangle. Both tools also provide tutorial information to help you better grasp the concept: UnitConversion.org's Degrees to Radians Conversion Quick and easy to use, enter your angle in degrees or radians and the other unit will be provided instantly. TutorVista.com's Inverse Trig Functions Find the inverse functions in degrees and radians. The needed formulas are provided as a reference. Enter the numbers in the respective input field, Now click the button Solve to get the difference, Finally, the actual and the estimated difference of two numbers. This resource will use the trig identities to simplify it. Well, since we already know that addition and subtraction are two almost the same operation, just with inverted signs, we can easily make the sin and cos difference identities using the formulas above: Sine difference formula:sin( - ) = sin()cos() - cos()sin(), Cos difference formula:cos( - ) = cos()cos() + sin()sin(). As a result, we find the initial value by using the new ones instead, applying the sum or difference formula.

The following tools introduce those theorems: CalculatorSoup.com's Triangle Theorem Learn more about six triangle theorems and how to solve them using the provided tutorial information. It includes a tutorial on angular size and examples of real world uses, such as measurements in astronomy. Some tutorial information about Heron's Formula is also included. A step-by-step explanation is provided with your results. Each (except for cotangent) features the needed formula and a diagram. WebMath.com's Simplify a Trigonometric Expression Enter your expression. As SparkNotes.com explains a vector is essentially a line segment in a specific position, with both length and direction, designated by an arrow on its end. Learn more about vectors using the resources below: MathIsFun.com's Vector Enter vectors as magnitude and angle or as x,y coordinates and see how they interact on the graph.
