Question

Write all formulas kf trigonometric

Answer 1

formula's you should know,

(for triangle ABC right angled at B)

sin C = perpendicular/hypotenuse = AB/AC
cos C = base/hypotenuse = BC/AC
tan C = perpendicular/base = AB/BC

And,

sin A = 1/cosec A
tan A = 1/cot A
cos A = 1/sec A
[instead of theta I used A]

trigonometric ratios are given in IMG.

And,

sin(90-A) = cos A
tan(90-A) = cot A
sec(90-A) = cosec A


tan A = sin A/cos A
cot A = cos A/sin A
