Trigonometric Functions and Applications

This video tutorial by Vasi on Jig's channel explains the car formula in trigonometry, focusing on the relationship between cosine, the adjacent side, and the hypotenuse. The tutorial covers three problem types: finding the adjacent side, the hypotenuse, and the angle, using the car formula. Each problem is solved step-by-step, demonstrating the application of the formula and the use of a calculator for cosine values.

What does the 'C' in the CAR formula represent?

• Circle

• Cosine

• Cotangent

• Cosecant

In the CAR formula, what does the 'A' stand for?

• Arc

• Adjacent

• Area

• Angle

What is the 'H' in the CAR formula?

• Height

• Horizontal

• Hypotenuse

• Horizon

The CAR formula is part of which mnemonic?

• PEMDAS

• BODMAS

• SOHCAHTOA

• SK

What is the primary use of the CAR formula?

• To determine the tangent of an angle

• To find the sine of an angle

• To calculate the area of a circle

• To find the cosine of a triangle

Which side is known as the adjacent side in a triangle?

• The side opposite the angle

• The shortest side

• The side next to the angle

• The longest side

In the first problem type, what is unknown?

• Angle

• Adjacent side

• Hypotenuse

• Opposite side

What is the value of cos 30° used in the first problem?

• 0.5000

• 0.7071

• 0.8660

• 1.0000

How do you solve for the adjacent side when given the hypotenuse and angle?

• Multiply the hypotenuse by the sine of the angle

• Divide the hypotenuse by the sine of the angle

• Divide the hypotenuse by the cosine of the angle

• Multiply the hypotenuse by the cosine of the angle

What is the first step in solving for the adjacent side using the CAR formula?

• Multiply both sides by the hypotenuse

• Divide both sides by the hypotenuse

• Multiply both sides by the adjacent side

• Divide both sides by the adjacent side
