Answer 1

force x displacement is formula of workdone ......n cos or sin is just the angle .....of frame from which it has been applied

Answer 2

Heya mate, Here is ur answer

Basically, what is
$\cos( \beta )$
It is the angle ratio of base/hypotenuse in a right angled triangle.

The formula mentioned above

$f \times d \times \cos( \beta )$

gives work done by a body.

You must have heared from ur teachers that When a body is at 90° , work done is 0 .

Why is it so❓❓

This is because the value of cos 90°=0 .

So, when you will use the formula of work done, work will come out to be 0 .

$w = f \times d \times \cos( \beta )$

$w = f \times d \times \cos(90)$

Because the angle is 90°

$w = f \times d \times 0$

As cos 90°=0

w=0 .

So, work done is 0 .
