What is inverse trig and how does it relate to what we know

The video tutorial covers solving triangle problems, focusing on finding missing sides and angles using trigonometric functions. It explains solving for Theta, using inverse operations, and applying cosine inverse to find angles. The tutorial includes practical examples and calculator instructions.

What trigonometric function is used to find an angle when the adjacent side and hypotenuse are known?

• Secant

• Cosine

• Sine

• Tangent

Which mathematical concept involves operations that reverse the effect of each other?

• Associative operations

• Commutative operations

• Inverse operations

• Distributive operations

What is the relationship between secant and cosine?

• Secant is the reciprocal of cosine

• They are unrelated

• Secant is the inverse of cosine

• They are equal

Why can't secant be used to find the angle directly in trigonometric equations?

• Secant is not defined for all angles

• Secant does not undo cosine

• Secant is not a trigonometric function

• Secant is only used for side lengths

What function is used to find an angle from its cosine value?

• Tangent

• Inverse cosine

• Sine

• Cosine

What is the notation used for the inverse cosine function?

• cos^1

• cos^0

• cos^2

• cos^-1

What is the angle in degrees when the cosine inverse of 9/11 is calculated?

• 40.000

• 35.097

• 30.000

• 45.000
