Question

A=Fs cosa Выразить F и S

Answer 1

Fs=A/cosa

F=A/s*cosa

S=A/F*cosa

Answer 2

F=A/s cos a

s=A/F cos a

Answer 3

To express F and S in terms of A and cos(a), we can use trigonometric identities. Let's start by writing the equation:

A = F * S * cos(a)

To solve for F and S, we'll isolate them on one side of the equation. Divide both sides of the equation by (S * cos(a)):

A / (S * cos(a)) = F

Now, divide both sides of the equation by F:

A / (F * cos(a)) = S

So, the expressions for F and S in terms of A and cos(a) are:

F = A / (S * cos(a))

S = A / (F * cos(a))
