Step-by-step explanation:

y = -3x² + mx + 10

dy/dx = -6x + m.

When dy/dx = 0, -6x + m = 0. => x = m/6.

We have y = -3(m/6)² + m(m/6) + 10 = 37.

=> -m²/12 + m²/6 = 27

=> -m² + 2m² = 324

=> m² = 324

=> m = 18 or m = -18.

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):

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