What is the value of $$\tan 45^\text{o}$$ ?

The value of $$\tan 45^\text{o} = 1$$ .

What is the value of $$\text{sine} 30^\text{o}$$ ?

The value of $$\text{sine} 30^\text{o} = \frac{1}{2}$$ .

What is the value of $$\text{cosine} 60^\text{o}$$ ?

The value of $$\text{cosine} 60^\text{o} = \frac{1}{2}$$ .

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides: $$a^2 + b^2 = c^2$$ .

How do you find the opposite side if you know the hypotenuse and the angle?

You can find the opposite side using the sine ratio: $$\text{opposite} = \text{hypotenuse} \times \text{sine} A$$ .

How do you find the adjacent side if you know the hypotenuse and the angle?

You can find the adjacent side using the cosine ratio: $$\text{adjacent} = \text{hypotenuse} \times \text{cosine} A$$ .

What is the tangent of an angle in terms of sine and cosine?

The tangent of an angle is the ratio of the sine of the angle to the cosine of the angle: $$\tan A = \frac{\text{sine} A}{\text{cosine} A}$$ .

What is the value of $$\tan 30^\text{o}$$ ?

The value of $$\tan 30^\text{o} = \frac{1}{\text{\text{sqr}(3)}}$$ .

What is the value of $$\tan 60^\text{o}$$ ?

The value of $$\tan 60^\text{o} = \text{\text{sqr}(3)}$$ .
