What is the definition of Secant (Sec) in trigonometry?

Back

Sec A = \frac{1}{\cos A}. It is the reciprocal of the cosine function.

Front

If Sin A = \frac{12}{13}, what is the relationship between Sin A and Cos A?

Back

Using the Pythagorean identity: Sin^2 A + Cos^2 A = 1, we can find Cos A.

Front

What is the formula to find Cos A if Tan A is given?

Back

Cos A = \frac{1}{\sqrt{1 + \tan^2 A}}.

Front

What is the definition of Cosecant (csc) in trigonometry?

Back

Csc A = \frac{1}{\sin A}. It is the reciprocal of the sine function.

Front

If Tan A = \frac{12}{5}, how can you find Sin A?

Back

Using the identity: Sin A = \frac{\tan A \cdot \cos A}{1 + \tan^2 A}.

Front

What is the Pythagorean identity in trigonometry?

Back

Sin^2 A + Cos^2 A = 1.

Front

How do you calculate the value of Sec A if Sin A is known?

Back

Sec A = \frac{1}{\sqrt{1 - \sin^2 A}}.

Front

What is the relationship between Sin, Cos, and Tan?

Back

Tan A = \frac{\sin A}{\cos A}.

Front

If you know the lengths of the opposite and adjacent sides of a right triangle, how do you find Tan A?

Back

Tan A = \frac{\text{Opposite}}{\text{Adjacent}}.

Front

What is the formula for finding Csc θ using a right triangle?

Back

Csc θ = \frac{\text{Hypotenuse}}{\text{Opposite}}.
