What is SOH-CAH-TOA? The sine of one of the angles of a right triangle (often abbreviated “sin”) is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle’s hypotenuse. The cosine (often abbreviated “cos”) is the ratio of the leng...
To dig deeper into particle dualism, in the second part, a class of models is proposed as a working framework. It encompasses some chaotic excitable reaction-diffusion systems, whose generalized susceptibilities make them compatible with quantized fields and excitations, of any desired symmetry group ...
If a right triangle is placed in a unit circle in the cartesian coordinate plane, with hypotenuse, base, and altitude measuring 1, x, y units respectively, then the unit circle identities can be given as,sin(θ)=y cos(θ)=x tan(theta)=sinθcosθ=yx sec(θ)=1x cosec(θ)=1y cot...
How do you know which angle is the elevation or depression? Explain the sine and cosine functions. What is the triangle side splitter theorem? Simplify the expressions by using a Double-Angle Formula or a Half-Angle Formula. a) \cos^2 (\frac{\theta}{2}) - \sin^2 (\frac{\theta}{2...
Let's begin with a simple extrinsic definition of dimension: The dimension of some (geometrical) object is the that of the lowest dimensional space it can be represented in; the dimension of a (vector) space is the number of coordinates required to describe a point in that space. Example:...
