Is this an identity? <br> 1+sec^2x=tan^2x

amid [387]

No, the correct identity is $\tan^2(x)+1=\sec^2(x)$ . It is obtained by dividing the both sides of the Pythagorean Trigonometric Identity by cos²(x):

$\sin^2(x)+\cos^2(x)=1\\\\
\dfrac{\sin^2(x)+\cos^2(x)}{\cos^2(x)}=\dfrac{1}{\cos^2(x)}\\\\
\dfrac{\sin^2(x)}{\cos^2(x)}+\dfrac{\cos^2(x)}{\cos^2(x)}=\dfrac{1}{\cos^2(x)}\\\\
\boxed{\tan^2(x)+1=\sec^2(x)}~~\blacksquare$

Determine the percent of change? original: 50 new: 150.

Reptile [31]

Hi there! The percentage of change is 200%

We can find the percentage of change using the following formula:
$\frac{new-original}{original} \times 100$

When we fill in this formula, we get the following:
$\frac{150-50}{50} \times 100 = \frac{100}{50} \times 100 = 2 \times 100 = 200$

Therefore, the percentage of change is 200%
