Question

how we learn the formula of sin,cos,tan and other give me Short form

Answer 1

hey there,

The sine of one of the angles of a right triangle (often abbreviated "sin") is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle's hypotenuse. The cosine (often abbreviated "cos") is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated "tan") is the ratio of the length of the side opposite the angle to the length of the side adjacent.

Hope this helps!

Answer 2

(S)ome (P)eople (H)ave

(S)in = (P)erpendicular/ (H)ypitanous

(C)urly (B)rown (H)air

(C)os = (B)ase/(H)ypitanous

(T)urn (P)ermanently (B)lack

(T)an = (P)perpendicular/ (B)ase

And for cosec, sec, cot it's just the opposite
