Trigonometry and Pythagoras Theorem

Question 1

Define the Pythagoras Theorem

Answer 1

a^2 + b^2 = c^2

c is the hypoteneus of the triangle.

Can only be applied on a right-angle triangle.

Question 2

Sides of Trigonometry

Define Hypotenous

Answer 2

The longest sideof a right-angle triangle

Question 3

Sides of Trigonometry

Define Opposite

Answer 3

The one side across the given angle.

Question 4

Sides of Trigonometry

Define Adjacent

Answer 4

The side next to the given angle.

You can simply find the adjacent side by the process of elimination.

Question 5

Main functions of Trigonometry

What is the Tan Equation?

Answer 5

TOA
Tan (Θ) = Opposite/Adjacent

Question 6

What is the Cos Equation?

Answer 6

CAH
CAH (Θ) = Adjacent/Hypotenous

Question 7

What is the Sin Equation?

Answer 7

SOH
SOH (Θ) = Opposite/Hypotenous

Question 8

How do we find the Θ using the Main Functions?

Answer 8

Tan (x) = Opposite / Hypotenous
x = tan^-1 (Opposite / Hypotenous)

Same applies for the other functions as well.

Do not input * in the last step, tan^-1 Opposite/ Hypotenous is enough.
