Question

notes on trigonometry.

expecting a good content ans!

Answer 1

hey here's the answer to your question...

Trigonometric functions:-
• Angles
• Functions of Acute Angles
•Functions of General Angles
• Tables of Trigonometric functions

Trigonometry of Triangles:-
•Law of Cosines
•Law of Sines
•Solving General Triangles
•Areas of triangles
• Solving right triangles

Functions:-
Circular functions
Periodic and Symmetric Functions
Graphs Cosine and Sine

Trigonometric identities:-
Addition identities
Double angle and half angle identities
Tangent identities
Product Sum and Sum Product Identities
Fundamental identities

The trigonometric ratios are the ratios between the two sides of a right angled triangle with respect to an angle and hence they are real numbers. The angle 0 taken into consideration may be acute,obtuse or right angled. Various trigonometry formulas which must be remembered are as the follows:-

(1) sin² 0+cos² 0=1
(2) sec² 0-tan² 0=1
(3) cosec² 0-cot² 0 =1
(4) sin 0 cosec 0= tan 0 cot 0= sec 0 cos 0=1
(5) sin² 0+cos² 0= 1 so each of them is numerically less than 1.
I can't type the rest of them so u can see on the link below...
