What is the Pythagorean identity involving sine and cosine?

The Pythagorean identity states that $$\sin^2\theta + \cos^2\theta = 1$$ .

How do you find the cosine of an angle if you know the sine?

You can use the Pythagorean identity: $$\cos\theta = \sqrt{1 - \sin^2\theta}$$ .

What is the value of $$\csc\theta$$ if $$\sec\theta = -7$$ and $$\tan\theta > 0$$ ?

$$\csc\theta = \frac{7\sqrt{3}}{12}$$ .

What is the relationship between the secant and cosine functions?

The secant function is the reciprocal of the cosine function: $$\sec\theta = \frac{1}{\cos\theta}$$ .

What is the definition of the cotangent function?

The cotangent function is defined as $$\cot\theta = \frac{\cos\theta}{\sin\theta}$$ .

What is the relationship between tangent and cotangent?

Tangent and cotangent are reciprocals: $$\tan\theta = \frac{1}{\cot\theta}$$ .

If $$\tan\theta > 0$$ , in which quadrants can theta be located?

Theta can be located in the first or third quadrants, where tangent is positive.

What is the formula to convert from radians to degrees?

To convert from radians to degrees, use the formula: $$\text{Degrees} = \text{Radians} \times \frac{180}{\pi}$$ .
