Answer 1

Answer on Question #58928 – Math – Trigonometry

Question

The value $\frac{\pi}{4}$ is a solution for the equation $3\sqrt{2}\cos\theta + 2 = -1$.

False

True

Solution

If $\theta = \frac{\pi}{4}$, then $3\sqrt{2}\cos\theta + 2 = 3\sqrt{2}\cos\left(\frac{\pi}{4}\right) + 2 = 3\sqrt{2} \cdot \frac{\sqrt{2}}{2} + 2 = 3 = 2 = 5 \neq -1$, hence $\theta = \frac{\pi}{4}$ is not a solution for the equation $3\sqrt{2}\cos\theta + 2 = -1$.

Thus, the statement in question is false.

**Answer:** False.

Question

There is no solution to the equation $\csc x = 0$.

True

False

Solution

$\csc x = 0,$

$$\frac{1}{\cos x} = 0,$$

Hence there is no solution to the equation $\csc x = 0$.

**Answer:** True.
