When we “see” a sound wave projected onto a visual screen, we see a wave. We describe music in terms of waves, in cycles per second or Hz. We use wave talk to discuss notes, speaking in frequencies and amplitudes. But then, without warning, someone starts spewing trigonometry at us like a high school mathematics ...
The Pythagorean theorem, special right triangles, trigonometric functions sine, cosine, tangent, law of sines, and law of cosines can be overwhelming to students in geometry and trigonometry. This article will be a clear, concise guide for all of these topics involving triangles. A triangle is a 3-sided geometric figure, whose sides are line segments, with ...
Trigonometry is perhaps one of the most widely used forms of mathematics in the fields of construction and engineering. This is because in order for whatever is being built to be functional and sturdy, precise math needs to be used to calculate exact values. If the blueprints of a project are inaccurate, then the flaws ...
A special note about this before we begin: this is only for the AP Calculus (AB) class because this is what i took I know that for the (BC) exam you need to know more methods of integration and how to do certain types of sequences and series. Thinking about taking AP Calculus? Can’t make ...
