Question

what is sin,cos,tan,cot,all

Answer 1

sin stands for sine
cos stands for cosine
tan stands for tangent
cot stands for cotangent

in a right angled triangle
tete is angle
sin teta = perpendicular/ hypotenuse
cos teta = base/ hypotenuse
tan teta = perpendicular / base
cot = base/ perpendicular

Answer 2

1)sine(sin) is defined as the a ratio between the length of perpendicular and hypotenuse

2)cosine (cos) is defined as the ratio of length of base and hypotenuse .
3)tangent(tan)is defined as the ratio between the length of perpendicular and base
4) cotangent(cot) is defined as the ratio between the length of base and perpendicular.
5)secant(sec) is defined as the ratio between the length of hypotenuse and base.
6)cosecant(cosec)is defined as the ratio between the length of hypotenuse and perpendicular.

Formula of
1)sin theta = perpendicular/hypotenuse
2)cos theta=base/hypotenuse
3)tan theta= perpendicular/base
4) cot theta=base/perpendicular
5) sec theta=hypotenuse/base
6)cosec theta = hypotenuse/perpendicular.
