What is Law of Cosine?
The Law of Cosines is used to find the remaining parts of an oblique (non-right) triangle when either the lengths of two sides and the measure of the included angle is known (SAS) or the lengths of the three sides (SSS) are known.

=length of side c
=length of side a
=length of side b

What is Inverse Trig?
Inverse trigonometric functions are simply defined as the inverse functions of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant functions.

What is pythagorean theorem?
A theorem attributed to Pythagoras that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

What does SSA mean in geometry?
"SSA" means "Side, Side, Angle" "SSA" is when we know two sides and an angle that is not the angle between the sides.

What is Pre- Calculus?
The main topics in the Precalculus course are com- plex numbers, rational functions, trigonometric functions and their inverses, inverse functions, vectors and matrices, and parametric and polar curves.

What is the standard form for a Linear Equation?
The standard form of a linear equation is Ax+By=C A x + B y = C .

What is difference between SAS and SSA?
SSA stands for side side angle postulate. In this postulate of congruence, we say that if two sides and an angle not included between them are respectively equal to two sides and an angle of the other triangle then the two triangles are equal. SAS stands for side angle side.

What is the formula for inverse trig?
the function y = f(x), and x = g(y) then the inverse function can be written as g = f-1, This means that if y = f(x), then x = f-1(y). An example of inverse trigonometric function is x = sin-1y.
