Derivative of tan(x) = sec²(x)

Step-by-step explanation:

Step 1: Define

$\frac{d}{dx} [tan(x)]\\x = \pi$

Step 2: Differentiate

Differentiate: $\frac{d}{dx} [tan(x)] = sec^2(x)$

Step 3: Evaluate

Substitute in x: $sec^2(\pi)$
Evaluate: $1$

If the measure of angle is θ is 7pi/4 , which statements are true?

Hoochie [10]

Answer:

$\checkmark$ $\sin\theta=-\frac{\sqrt{2}}{2}$

$\checkmark$ $\tan \theta = -1$

$\checkmark$ The measure of the reference angle is $45^{\circ}$

Step-by-step explanation:

The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have $360-315=\boxed{45^{\circ}}$ (*Note: $\frac{7\pi}{4}=315^{\circ}$ , use $\pi=180^{\circ}$ to convert to degrees)
