Find all solutions in the interval [0, 2π).

7 tan3x - 21 tan x = 0

Hence, all the solutions in the interval [0,2π) are:

We are asked to find the solution of the trignometric identity which is given by:

On dividing both side by 7 we get:

i.e.

Either

i.e.

or

If

and if

Hence, all solutions are:

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
