Question

can you give me all things
about trignometry?

Answer 1

Learn all the sine values,cos values etc.So,that you will feel easy while solving sums.Then,you must know about the signs of cos,sin etc in the four components.You should be able to convert sin theta into cos theta.

Answer 2

heya,
about trigonometry.

trigonometry is the best part of maths. it is about the studies of relationships between lengths and angles of triangles. 

now about sin, cos, tan.
sin A = opposite/ hypotenuse.
cos A = adjacent/ hypotenuse.
tan A = opposite/ adjacent.

Sine = Opposite ÷ Hypotenuse
Cosine = Adjacent ÷ Hypotenuse
Tangent = Opposite ÷ Adjacent

thank you. i hope this will helps you.
