What Does θ Mean in Trigonometry? θ in trigonometry is used as a variable to represent a measured angle. It is the angle between the horizontal plane and the line of sight from an observer's eye to an object above. θ can be referred to as the angle of elevation or angle of depress...

Trigonometry is an importantbranch of mathematicsthat is used to study the relationship between ratios of the sides of a right-angled triangle with itsangles. The word “trigonometry” is derived from the Greek words, “trigon” and “metron”. The word “trigon” means a triangle and the wor...
= o h cos! = a h tan! = o a A simple way to remember these rules is the mnemonic SOH CAH TOA, where S stand for sinθ, O stands for opposite and so on. It is important to understand that sinθ does not mean sin ×θ as you would expect. It is actually a kind of number...
Since in Euclidean trigonometry we have m=tanϕ, in special relativity we have (v/c)=tanhθ. Relative slope would be like mrel=tan(ϕB−ϕA)=mB−mA1+mBmA (which is invariant of choice of grid orientation)... note that slopes don't "add" or "subtract". Relative ...
In trigonometry, we can use right triangles to evaluate the trigonometric functions of an angle. That is, we have specific ratios of the lengths of the sides of a right triangle that are equal to each of the trigonometric functions of the acute angles in a right triangle....
What is the cosine of an angle in relation to trigonometry? (a) What does the term inverse trigonometric function mean? (b) How are inverse trigonometric functions used? What is the inverse of sin? When is sin inverse imaginary? What is the cosine of 5pi over 2? What is the cosine of...
While all of this talk about the angles and sides of right triangles and their correspondence to one another through the beauty and magnificence of trigonometry is indeed lovely, it might leave you wondering a bit about the “Why?”“What?” and “When?” of it all. By which I mean: Wh...
What does SOH CAH TOA mean? "SOHCAHTOA" is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2) ...
