How to Use the Half-Angle Formula to Solve Equations To solve an equation using a half-angle formula, substitute the known values where they belong and then solve. The trick is keeping track ofθandθ2. For instance, considersin15∘=a. To use a half-angle formula to solve this, remem...
Underlying these simple equations is an equally simple intuition regarding the relationship between price and value. In essence, Tobin’s Q Ratio asserts that a business (or a market) is worth what it costs to replace. The cost necessary to replace the business (or market) is itsreplacement v...
The method is explained in Graphing Quadratic Equations, and has two steps: Find where (along the horizontal axis) the top occurs using −b/2a: t = −b/2a = −(−14)/(2 × 5) = 14/10 = 1.4 seconds Then find the height using that value (1.4) h = −5t2 + 14t + ...
The six basic trigonometric identities are the equations of the six trigonometric functions. Those trig functions are sine = O/H, cosine = A/H, tangent = O/A, secant = H/A, cosecant = H/O, and cotangent = A/O, where H is the hypotenuse, O is the opposite side, and A is the...
I recommend usingTeX All the ThingsChrome Extension for viewing math equations on this page. Do expect mistakes, misunderstanding, and shallow interpretation as I am an ignorant PhD student. Please correct me if you found one of those mistakes. I will really appreciate it. ...
Domain: Based on the types of equations used to define the functions. Includesalgebraic functions,logarithmic functions, andtrigonometric functions. Function Notation Function notationtells you that the equation you’re working with meets the definition of a function. ...
For instance, if a presenter is discussing statistical probability, instead of explaining probability in terms of equations, it may make more sense for the presenter to make up a hypothetical example. This could be a story about a girl, Annie, picking 10 pieces of candy from a bag of 50 ...
For researchers and professionals who want to remove outliers, multiple regression equations are the preferred method. Regression analysis provides a more accurate result and more reliable data at the conclusion of a study. Aside from regression analysis, there are also more basic ways of adjusting ...
A mathematical sequence is a set of numbers written in a certain order. For example, suppose a ball is dropped from a height of 32 inches. Each time the ball hits the ground, it bounces to one-half its original height. The heights of each bounce could be written as the following ...
