Sin squared x equals 3 cos squared x
The domain of the function is the set of all x's that are suitable for the given equation. In the problem, we are asked to determine the equation with the most restricted domain. Option A can have x from negative infinity to positive infinity as well as option B and option D. OPtion C can only have x equal to zero and all positive numbers. Hence the answer is C. hope that helped
The irrational number on set B is given by:
<h3>What are irrational numbers?</h3>
Irrational numbers are numbers that cannot be represented by fractions. The two most common examples are:
In the set B given in this problem, the only number that is irrational is , as it is a non-exact root.

Hi. Unfortunately there is no statement to determine if it's true or not. However, I would just give the correct statement.
Secant function is the inverse of cosine. In trigonometry, a right triangle has one 90 degrees angle. It consists of the hypotenuse(h), the adjacent side (a), and the opposite side(o), with respect to the angle. For cosine, it is adjacent over hypotenuse. Since secant is the inverse, it would be hypotenuse/adjacent. Hypotenuse is the longest side.
Hence, sec theta = 15/9
I hope this helps :)
