How do you remember sine cosine and tangent?

The sine, cosine, and tangent ratios in a right triangle can be remembered by representing them as strings of letters, for instance SOH-CAH-TOA in English: Sine = Opposite ÷ Hypotenuse. Cosine = Adjacent ÷ Hypotenuse. Tangent = Opposite ÷ Adjacent.

How do you memorize trig tables?

Tricks To Remember Trigonometry Table
  1. sin x = cos (90° – x)
  2. cos x = sin (90° – x)
  3. tan x = cot (90° – x)
  4. cot x = tan (90° – x)
  5. sec x = cosec (90° – x)
  6. cosec x = sec (90° – x)
  7. 1/sin x = cosec x.
  8. 1/cos x = sec x.

How do you introduce trigonometry to students?

Introducing Trigonometry
  1. Measure the lengths of the sides of sets of similar right angled triangles and find the ratio of sides.
  2. Investigate the relationship between these ratios and the angle size.
  3. Use calculators or tables to find the sine, cosine and tangent of angles.

Why is Trig so hard?

With trigonometry, you have to remember what sine and cosine mean, for example. You have to remember what they represent and the various ways they impact angles and lengths. Trigonometry is difficult because it involves a lot of memorization of different functions which can then deviate into other functions.

Is Trig a calculus?

It seems as though calculus applies trigonometric functions in the same way algebra does, i.e. it's a system of operations which doesn't depend on things like trig' in any way, but rather serves as a foundation/context for using trig'.
