Question

trigonometry basics?

Answer 1

remember the basic trigonometric ratio
sin x =p/h
cos x=b/h
tan x =p/b
where x is the angle and p is perpendicular
b is base and h is hypotenuse.

Answer 2

trigonometry basics
*sin theta = opposite side /hypotenuse
*cos theta =adjacent side /hypotenuse
*tan theta =opposite side /adjacent side
*cosec theta =hypotenuse /opposite side
*sec theta =hypotenuse /adjacent side
*cot theta =adjacent side /opposite side
cosec = 1/sin
sec =1/cos
tan =sin / cos
