Question

Arjun saw an equation written like $4sin2\theta =5$. State if the given equation is true or false?

• A. True
• B. False

Answer 1

The correct option is B

False

$4sin2\theta =5$

$sin2\theta =\frac{5}{4}$

Since $-1\le sin\theta \le 1$, $sin\theta$ cannot take a value more than 1.

Since $\frac{5}{4}$ is more than 1, it is not a possible value of sine.

Hence, the given equation is false.
