Question

Assertion(A). The function $f\left(x\right)=\sin x$ is symmetric about the line $x=0$
Reason $\left(R\right)$ : Every even function is symmetric about Y-axis

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

Answer: (D)

A is false but R is true

$f\left(x\right)=\sin x$ is an odd function
So it is not symmetric about the line $x=0$ (y axis)
Every even function is symmetric about $x=0$ (y axis)
