Evaluate the six trigonometric functions given cosine

The video tutorial discusses solving a problem without a given triangle by understanding cosine as a comparison between the adjacent side and hypotenuse. It guides through drawing a triangle, identifying its sides, and calculating trigonometric functions like sine, cosine, and tangent. The tutorial concludes with finding reciprocals and emphasizes understanding trigonometric functions to create triangles.

What is the primary comparison made in the cosine function?

• Opposite side to hypotenuse

• Adjacent side to hypotenuse

• Hypotenuse to opposite side

• Opposite side to adjacent side

When constructing a triangle, where should the angle Theta be placed if the adjacent side is known?

• At the hypotenuse

• At the opposite side

• At the center of the triangle

• At the adjacent side

Which theorem is used to determine the opposite side in a triangle?

• Sine rule

• Pythagorean theorem

• Cosine rule

• Tangent rule

What is the reciprocal of the sine function called?

• Cosecant

• Secant

• Tangent

• Cotangent

If the tangent of Theta is 1, what is the relationship between the opposite and adjacent sides?

• Opposite side is equal to the adjacent side

• Opposite side is half the adjacent side

• Opposite side is twice the adjacent side

• Opposite side is zero
