The graph of an inverse trigonometric function passes through the point (1, pi/2). Which of the following could be the equation

rodikova [14]

Answer: C) $y=sin^-1 x$

Step-by-step explanation:

Since, the graph of an inverse trigonometric function will pass through the point $(1,\frac{\pi}{2})$ ,

If this point satisfies the function,

For the function $y=cos^{-1} x$

If x = 1

$y=cos^{-1}1=0$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cos^{-1} x$ ,

⇒ The graph of $y=cos^{-1} x$ is not passing through the point $(1,\frac{\pi}{2})$

For the function $y=cot^{-1}x$

If x = 1

$y=cot^{-1}1=\frac{\pi}{4}$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cot^{-1}x$ ,

⇒ The graph of $y=cot^{-1}x$ is not passing through the point $(1,\frac{\pi}{2})$

For the function $y=sin^{-1} x$

If x = 1

$y=sin^{-1}1=\frac{\pi}{2}$

Thus, $(1,\frac{\pi}{2})$ is satisfying function $y=sin^{-1} x$ ,

⇒ The graph of $y=sin^{-1} x$ is passing through the point $(1,\frac{\pi}{2})$ .

For the function $y=tan^{-1}x$

If x = 1

$y=tan^{-1}1=\frac{\pi}{4}$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cos^{-1} x$ ,

⇒ The graph of $y=tan^{-1} x$ is not passing through the point $(1,\frac{\pi}{2})$ .

Hence, Option C is correct.

Solve using algebraic equation: <br> 5sin2x=3cosx

disa [49]

$\bf 5sin(2x)=3cos(x)\qquad \qquad sin(2\theta)=2sin(\theta)cos(\theta)\qquad thus
\\\\
5[2sin(x)cos(x)]=3cos(x)\implies 10sin(x)cos(x)=3cos(x)
\\\\
10sin(x)cos(x)-3cos(x)=0\impliedby \textit{taking common factor}
\\\\\\
cos(x)[10sin(x)-3]=0\implies 
\begin{cases}
cos(x)=0\to &\measuredangle x=cos^{-1}(0)
\\\\
sin(x)=\frac{3}{10}\to &\measuredangle x = sin^{-1}\left( \frac{3}{10} \right)
\end{cases}$

Which statement is true about percent yield?

Lera25 [3.4K]

Answer: Dividing the actual yield by the theoretical yield and multiplying by 100 indicates percent yield.

Step-by-step explanation:

We know that the percent yield is the percent ratio of actual yield to the theoretical yield ( since the actual yield is commonly less than the theoretical yield.), then multiply with 100.

Hence, the true statement about percent yield is "Dividing the actual yield by the theoretical yield and multiplying by 100 indicates percent yield."
