The value of x is for the given trigonometric function is found as: x = 0.1303 + 1/15 *2nπ.
Explain about the solutions of trigonometric functions?
- The fact that too many trigonometric equations have infinitely multiple solutions rather than two makes a significant distinction.
- We will learn how to interpret one solution of an equation in terms of all the other answers by using the inverse trigonometric functions.
The given expression is:
16 cos(15x) + 8 = 2
On simplification:
cos(15x) = (2-8)/16
cos(15x) = -3/8
15x = arcos ( -3/8 )
15x = 2π - arcos ( -3/8 )
15x = arcos ( -3/8 ) + 2nπ ;or
15x = 2π - arcos ( -3/8 ) + 2nπ ; n ∈ Z
So,
15x = 1.955 + 2nπ
x = 1/15(1.955 + 2nπ)
x = 0.1303 + 1/15 *2nπ , n ∈ Z
Thus, the value of x is found as: x = 0.1303 + 1/15 *2nπ.

So all the numbers divisible by 8, 15, and 21 are all the multiples of 280.
The smallest 6-digit number is 100,000 .
100,000 / 280 = 357.1 , so the next whole-number multiple is the 358th one.
280 x 358 = 100,240 .
You can tell right away that this is the smallest one that qualifies,
because if you take away 280 and go to the next smaller multiple,
it won't have 6 digits anymore.
