Right-Angle Trigonometry

Question 1

What is a Trigonometric Function?

Answer 1

A trigonometric function is a function whose rule is given by a trigonometric ratio that compares the lengths of two sides of a right triangle.

Question 2

What is the Formula for Sin of Theta?

Answer 2

Sin Of Theta = opposite divided by the hypotenuse.

Question 3

What is the Formula for Cosine of Theta?

Answer 3

Cosine Of Theta = adjacent divided by the hypotenuse.

Question 4

What is the Formula for Tangent of Theta?

Answer 4

Tangent of Theta = opposite divided by the adjacent.

Question 5

What is the Formula for Cosecant of Theta?

Answer 5

Cosecant of Theta = hypotenuse divided by opposite. The Cosecant of Angle Theta is the reciprocal of the sine function.

Question 6

What is the Formula for Secant of Theta?

Answer 6

Secant of Theta = hypotenuse divided by adjacent. The Secant of Angle Theta is the reciprocal of the cosine function.
