Sin, cos, and tan are the three primary trigonometric ratios where each of which gives the ratio of two (of three) sides of a right-angled triangle.

How to use a Sin Cos Tan Chart?

A right triangle has one angle that is 90°. The other two angles are always less than 90 ° and together add up to 90°. Note that the triangle on the right has 3 angles a, b, and c and 3 sides, A, B, and H, and 3 angles a, b, and c. The side "opposite" angle (in this case) is labeled with a capital letter corresponding to the label on the angle. The side opposite the right angle, H, is always the longest side and is called the hypotenuse.

Some rules/guidelines for trigonometry of right triangles

We can use ratios (or the quotient) of the lengths of a right triangle's sides to figure out the angles in a right triangle. Three trigonometric ratios that we use in the geosciences are called the sine, the cosine, and the tangent, although they are often abbreviated sin, cos, and tan, respectively.

Because the trigonometric functions come up over and over, it is a good idea to figure out a way to remember their definitions. For most students the mnemonic SOH-CAH-TOA (said "so-Kah-toe-ahh") is helpful.
The mnemonic device uses the first letters in the following equations:

  • sin=opp/hyp (this is SOH, where S=sin, O=opposite and H=hypotenuse)
  • cos=adj/hyp (this is CAH, where c=cos, a=adjacent and H=hypotenuse)
  • tan=opp/adj (this is TOA, where t=tan, a=adjacent and O=opposite)

After downloading this sample chart and filling in the blanks, you can easily customize the style, typography, details, and appearance of your Sin Cos Tan Chart. If this isn't the right document that you are looking for, then certainly take a look at the other letters that has to offer. We have many letters ranging from cover letters to business letters and thank you notes.
