The sum of the three smallest positive values of theta such that 4(cos((theta)) = 1 is k(pi). find k.

We are given

We can divide both sides by 2

now, we can use trig identity

so, we can use it

we can take sin^-1 both sides

We can take first three positive value

First value is:

Second value is:

Third value is:

now, we can add them

now, we are given that sum is k(pi)

so, we can set them equal

Divide both sides by pi

and we get

................Answer

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
