Synthesize a table of full, detailed and easy to understand trigonometric formulas
This trigonometric formula table is a synthesis of trigonometric formulas learned in high school, including knowledge of trigonometric values of special arcs, trigonometric values of special angles, Basic solution formulas and trigonometric formulas.
1. Trigonometric formulas of special related arcs
- Two opposite arcs α and - α
- The two arcs complement each other α and π - α
- Two complementary arcs α and (π / 2 - α)
- Two bows are inferior to each other π
- Bows are worse than each other π / 2
Suggestions for special bow memory poetry :
Cos for, offset sine, sub cross, other pi tag.
The cosine of two opposite angles is equal.
The sins of the two offset angles are also equal.
The cross auxiliary angle is 2 sub-angles, the sine is equal to the other cosine.
Melting one corner with Cot another.
The solubility of the two angles less than pi is also equal.
2. Basic trigonometric formula and addition formula
- Basic trigonometric formulas
Suggestions for memorizing basic trigonometric functions :
The average sine cos average must be 1.
Sin binh is equal to the tag by the average tag 1.
Cos equals one on one plus tag comment.
One on the average sine is equal to 1 plus the average cotg.
One on cos average equals one plus tag comment.
Catching the effect.
Sin is on cos.
Cotg reformed.
Cos is on sin.
- Formula plus
Suggested public formula poetry .
Cos plus cos is equal to two cos cos
Cos minus cos must equal minus two sine sine
The sine plus sine is equal to two sine cos
Sin minus sine is equal to two cosine s.
Sine then sine cos cosine
Cos, cos sin cosine remember the minus sign
Total tangent, then total tang
Dividing one minus by tangent product, it's easy.
3. The trigonometric formula of doubling, triple and descending trigonometry
- Double recipe
Recommended poetry formula for duplicating :
The sine is twice equal to the sine cosine
Cos twice equal to cosine minus sinusoidal, equal to two cylinders minus 1, also equal to one minus two sine flasks.
Tang is doubled, we take 2 tangs divided by one minus the tang right.
- The formula of triple
Suggested poetry for the triple formula :
Multiply by 3 any angle.
Sin is three-four, Cos is four-three.
- Formula of downgrade
4. The trigonometric formula converts the product to the sum, the total achievement
- Formula to convert total achievements
- Formula to convert product into sum
5. Solution formulas of basic trigonometric equations
- Basic knowledge
- Special case
- Table of trigonometric values for some special sectors
